civiln00b, just to raise your confidence, one of my colleaque finished bachelor degree in engineering at 40 and was hired 1 year back. Reason: He was running a small business where he gained a valuable experiences from winning business to delivery. As our work is mostly project management for...

mechenddude, 1. to know whether in-built material model developed by software vendors is suitable to simulate your material or not. 2. You are right. We need this curve to find E value as mentioned by GBor.

Thanks GBor. Unfortunately, i cant provide this report. But, It is nothing unusual than steel material validation report except it is a polymer. I overlooked E value. Thanks again for pointing out.

Hello Users, I have a report which validates particular material model available in FEA by doing FEA tensile test against experimental tensile test data of the material. FEA tensile test process: Create specimen model - mesh - apply load - calculate displacement - calculate strain and...

Hello OP, i dont know what you have decided. But, this link may help you. http://www.rediff.com/money/2008/jul/01forbes.htm but, i had a better experience becuase i did not leave the start up company when it was important. Eventhough i was not rewarded interms of money, Still i maintain good...

Thanks for all replies and i am better now after reading info here and from other websites. Johnhors, i was just referring to the orientation as rb1957 said. Anyway that was the wrong discription. Question arised due to confusion from the example from abaqus manual, which i have given at the...

Prost, r u sure, 3d brick elements have 6 dof. Does not it have only 3 translation direction dof. Or, u meant to say shell element and membrane elements.

Hello users, Befor posting here, i have gone through previous posts regarding my doubt. Still, i am not clear. so my queries are interpretations of principal stresses. 1. Principal stresses are scalar or vector? If it is vector, then does it depend on the way of mesh is generated. 2. In...

Sorry users, I got the answer from other Thread. Answer: create a job and instead of submit, just click write input. Thanks.

Hello users, Is it possible to import Abaqus/cae file into Hypermesh. (Like Viceversa is possible with *.inp file format from Hypermesh). Thanks for any help.

Interesting Gbor. I did the same analysis in Hypermesh and i got what i expected(same disp and stress as static results). Another user did the same with patron and nastran and got the same. So i thought it is a problem with Hypermesh and Nastran interface. Now, you have a different...

Just a suggestion: If you use surface elements, can you check element normal and make it uniform.

Hello, I ran into another problem. As i said in my previous postm I did a static analysis for cantilerver beam with steel matl, and got displacement(25 mm) and von mises stress at fixed boundary (45 MPa). For the same model, i did the frequency response analysis expecting at 0Hz frequency...

GBor, Thanks. Excuse me for late reply. Definitely i do not have any power spectrum density data and even i have no clue how to do it in Nastran. I extraced normal modes and applied acceleration(15 m/s^2) at a range of freq of 0 to 60 Hz. At resonant freqency looked for displacement and...

Thanks Patprimmer. Nice writeup abt warpage. Though, 24 mm is possible, in our prototype part both warpage pattern and the dimesnion (around 12 mm in different location) both do not correlate with Moldflow. Investigation is going on. Still my question is unanswered regarding warpage plot...
