    Young's modulus

    Hi all, I have this confusing thought for a quite long time. Is there any relation between the time-independent Young's modulus with the time-dependent Young's modulus (instantaneous and equilibrium moduli or loss and storage moduli)? If yes, what is the equation to relate them? So many...

    Post-Buckling Analysis Didn't Work (at least for me).

    Hi all, I read the ABAQUS documentation regarding the post-buckling analysis (6.2.3 and 6.2.4). I tried to perform the post-buckling analysis using the IMPERFECTION command and RIKS step. However, the resulting shape of my sample (a bar with a rectangular cross section) did not tally with the...

    ABAQUS Unit Conversion for nanometer.

    Hi all, I ran a pre-buckling analysis using ABAQUS. However, I found the eigenvalue (in nN range) is not as what I expected (uN range). My initial guess for this problem is due to the unit conversion. I choose nanometer as my unit length. For Young's modulus value, I wrote 0.0000001 for 100...
