Many industries are realising that yesterday's answers are not always tomorrow's solutions. Companies are re-engineering their design through manufacturing processes with finite element analysis (FEA) design and simulation technology to provide better products, faster, and at a lower cost. The ANSYS family of products provides a very flexible engineering environment; it is integrated with more CAD packages than any other analysis package, and runs on a wide range of hardware from PCs to supercomputers. Worley FEA, exclusive distributors for ANSYS in Australia and NZ, invites you to the 1997 ANSYS Conference to see and hear about practical engineering applications of FEA technology. This three-day event will be held at the Sheraton Towers, Southgate, Melbourne on June 25-27, 1997. The first day will be devoted to training on advanced ANSYS capabilities conducted by ANSYS, Inc developers. This conference is your best opportunity to meet ANSYS users from a range of industries around Australia, and see how others are using the program. ANSYS, Inc developers and management, and Worley FEA's team of experienced analysts will be avaialble to discuss how ANSYS can help with your paritcular design needs. Who Should Attend? This conference is geared towards design engineers and FE analysts, as well as business and engineering managers. Attendees can learn more about the ANSYS program's capabilities, using FEA to simplify their product design / verification and prototyping processes, and maximize the benefits of their CAE/CAD investment.

Could someone please educate me as to what units most shock manufacturers quote their damping rates in? A vibrations text that I'm using uses units of mass per time (eg. kg/s or lbs/s). I need to be able to convert these units to those used by the shock manufacturer so I can select the proper rate for my application. Some rates that I've seen include in.lbs or just numbers. What do these mean? Your help would most kindly be apprecuiated.

If any manufacturer suggests that their system will do the job, suggest that a blind test be made. Three specimens should be stress relieved using normal methods and three specimens using the vibration method. Send the specimens to an independent lab for testing. I'll bet that the vibration-stress relief people will not submit to the tests. It has been tried before and no relief was found. Thermal methods of stress relief brings the state of stress within a body to a point where the material reaches a transition (phase) temperature. A relaxation takes place and the state of the material is "normalized." In order for vibration methods to work, a cold working process must take place. This means that the orginal residual state is masked by a higher state of stress. Since we are dealing with an oscillatory motion, the effective stress will be both tension and compression. If only tensile residual stresses were present in the first place, then the induced compressive stresses from the vibration would cause additional and unforseen problems. For most steels, they follow the max. shear failure law. This would create a failure in another direction. If you are trying to eliminate the progressive growth of cracks, I have tried a laser induced method that has shown to double the life of the specimen. Richard L.

Is there anyone out there that knows how to layout out the relative positions of the ring and pinion gears for starters? I have read SAE J543 and still have many questions. The modified addendum seems to be confusing the issue. Do you posistion the gears relative to one another based on their theoretical pitch diameter or the layout pitch diameter. Intuition would tell me to use the layout diameters, but I am trying to interpret some OEM data and things are not adding up. Thanks in advance and sorry if I posted this in the wrong place.

GREAT SOURCE OF MECHANICAL ENGINEERING RESEARCH DATA AVAILABLE: HERE'S HOW! I have been studying access to Defense Department technical/research reports, and the release and declassification of those technical reports. It turns out that there are millions of technical reports on every subject imaginable catalogued at the Defense Technical Information Center - DTIC: many of their reports are not classified, but are nevertheless still not accessible to civilian researchers, journalists and others, except through the Freedom of Information Act - FOIA. DTIC WEB SITE IS SANITIZED & WORTHLESS: DON'T BOTHER WITH IT DTIC does have a web site, but the indexes on that web site are extremely misleading. One, they only search back 10 years., and some of the journalistic research may require additional coverage. Second, and more important, the web site only includes public documents that are already available through NTIS-National Technical Information Services. In that regard, it's pretty worthless. So forget the web site and mail in your request directly. TECHNICAL DATA ON ALMOST ANY SUBJECT: NOT JUST DEFENSE TOPICS Bear in mind that the Defense Department has conducted research on literally any subject including the environment, oceanography, biology, medicine, chemistry and physics, history, animals, psychology and sociology, behavior, anthropology, archeology, engineering, safety, etc. etc. You name it, they've got it. HOW TO GET IT However, any person can get a complete list of these otherwise unavailable tech reports by using the Freedom of Information Act. Simply send a letter of request to Kelly D. Akers, Freedom of Information Act Manager, Defense Technical Information Center, Attn: DTIC-RSM, 8725 John J. Kingman Road, Suite 0944, Fort Belvoir, VA 22060-6128 USA. You should not need to call, but just in case, her phone number is 703-767-9194. WHAT TO ASK FOR In the letter, explain that you would like a complete computer-generated technical report bibliography (for all computer database years) for reports associated with the subjects and keywords XXXXXXX or YYYYYYY or ZZZZZZZ. Select your keywords or subjects carefully, no more than one dozen per request. Use the word OR between keywords, and include parentheses *s* with keywords to indicate plurals also. DTIC will process your request very literally, so pick your keywords with care. FOR EXAMPLE, *STRESS ANALYSIS*, *FINITE ELEMENT ANALYSIS*, MECHANICAL ENGINEERING, ETC. You can also request all reports by a particular author, or all reports by a particular contractor or company. Indicate whether you are a for-profit company, or a noncommercial requester. Fees are not likely to be more than a couple of dollars, but indicate in the letter that you will be willing to pay fees up to $20 without additional permission. This last sentence is important; DTIC will not process your request without a statement agreeing to pay fees. It takes about 3-4 weeks to get a response. Once you get the list of reports, you can select the ones of greatest interest or value and ask for those specific reports with another letter, if you want.

"It would be easier to spend *more* money if I had an *up-to-date* catalogue.") they never bothered to send me a new one or explain why they thought I should be satisfied with my old one. If it had been any other company, I would have stopped buying from them. But since even an old McMaster catalogue is *such* a good reference... Andrew MoskalikReturn to Top

Hi, I would like to seek your advice on the following: 1. It is possible to assign specific kekpoint number when creating it. Can the same thing be done for line and area? 2. It is possible to extract the keypoint number using APDL function kp(x,y,z). Is there similar functions for line, area and volume? 3. The death and live function allows one to put selected elements to death to simulate their absence. Can we achieve the same purpose by unselecting the element before runing the solution? What are the diffenences? Best regardsReturn to Top

My hair reaches the center of my back in a ponytail and I wear an earring. For interviews I have always worn clean jeans, nice shoes, a nice shirt, and a sport jacket (I despise ties). While I certainly have had a few people whom I could tell were put off by my appearance, the vast majority have been much more concerned with my GPA (at least within the first year or two out of school) and capability (for the last 12 -13 years). Shaving, actually, is one of my weak points :-). I would concentrate on presenting your accomplishments in an interview setting. In HP, we interview intensively and care about two main things: the person's past performance (which is the best indicator of future performance) and their ability to work with others. Just out of school, you don't have a lot of past performance, but you can concentrate on projects you worked on, initiatives you have taken, and your ability to get along with teams of co-workers. Present concrete examples. Prove to them you can solve their problems. |> Oh, well it may be time to conform.

What you do with your appearance is dependent on how important it is to you. I wouldn't cut my hair even if it meant that I'd have to work for 1/2 of my present salary, but that's me. |> .......

Hello, I have been trying to study fastener load distribution in splices and doublers using FEA (ANSYS in particular) with only limited success. I can get the peaking effect but the numbers are off as compared with hand calculations (Niu "Airframe Structural Design" pg 235). Below I briefly describe the problem and then my modeling method. I am hoping somebody can point out where I am going wrong. Problem: Consider a doubler configuration of two plates of equal thickness and material properties fastened together by a row of six fasteners. One of the plates carries a through load (axial loaded). I would like to study the effect of varying the diameter of one of the fasteners. Modeling: To model the plates I have used both shell and beam elements. Both of these give similar answers. In both cases, I used a separation distance equal to the distance from the mid-plane of one plate to the mid-plane of the other plate. The fasteners are modeled using beam elements with the diameter of the fastener used to calculate the required constants (area, Iyy, Izz, etc.). When I vary one of the fastener diameters, I get almost no change in load transfer for that fastener. Any suggestions? Regards, Carl SawyerReturn to Top
