    What really counts in judging component failure.( Max. Prince. Stress, von mieses.)

    Hallo dear Friends, I have a FEM model which should fullfil the technical Standard sent from OEMs. . Component stifness should be Not less than 200 N/mm under static loading. The question as Follow: 1. Who can explain me which type of Stress Evaluation really counts. And what is the idea...

    First career advice: how to deal with a bigheaded, pretiontious and concieted colleague?

    Hallo dear Friends, i am fresh Engineer working in a R&D fiel Since april 2015. I am disturbed by on of the employee Who started his Job in the Same Day with me. The difference between me and him is the degree. He is phi and i am M.Sc..the field of work is New to both of us but he is so...

    Eigen-value Analysis

    Hallo friends, I have calculated the eigenvalue of orthotropic plate in FEM, how i can calculate the eigen value analyically??? is it not (the critical buckling load/refference load)?? thanks!

    Load Displacment curve ?? the slope of the curve is E1 or E2 or E12?

    Hallo guys, it may be a simple question, i had to compare experimental result with FEM. in experiment my structure is less stiff than FEM for the case of compression 400mm specimen with 10mm thickness (orthotropic). 1- Why? 2-what is delta(F)/delta(u)=E. what is E in case of orthotropic...

    Abaqus Explicit/Dynamic: why it is not possible to use Augmented lagrange contact algorithm??

    Hallo friends, Abaqus Explicit/Dynamic: why it is not possible to use Augmented lagrange contact algorithm?? is it due to change in mass matrix during dynamic simulation. and what does general contact means??and how it works? Many thanks!

    Abaqus/Explicit error:THE ANALYSIS PARAMETER IS NOT A VALID PARAMETER IN ABAQUS EXPLICIT ???

    Hallo friends, i am modeling composite damage behaviour usisng damage criterion every thing works well until i got this error which i could not get any feedback about it how to solve this issue in which module does this error depends on (step)?? many thanks in advance!
