    Axisymmetrie problem

    hello, I simulate a mechanical joining method "clinching": 2D Axisymmertic in Dynamic Impl I try stamping two sheets (deformable) whit a punch rigid. I used simple contact friction 0.2 During the simulation the edges in the end of the sheets don't move. The stress around the punch becomes...

    Damage Evalution Problem

    Hello, I study a damage problem (Dynamic-Temp_disp Exp) between a tack (nail) and two sheets. At th end of the simulation there is no damage on the sheets Tack is analytical rigid Sheets are deformable I use a JK platicity and a JK damage Thanks

    enegy balance problem

    Hello , I try to simulate quenching of a steel strip with abaqus standard, the step is coupled temp-displacement I can’t find the balance energy between internal energy and work external. In my model ALLWK is very excessive ETOTAL is not constant, it increases. I don't understand why it is...

    Coupled Temp-displacement Convergence problem

    Hello, I m analyzing the rapid cooling (about 700C°C/s) of steel plate (thickness 1mm) in Abaqus/Standard. I have same convergence problem like : ***ISOTROPIC HARDENING PLASTICITY DID NOT CONVERGE FOR ELEMENT PLATE-1 ***THE SYSTEM MATRIX HAS 6 NEGATIVE EIGENVALUES I tried - reduce the...

    Subroutine DFLUX in ABAQUS/Explicit

    Hello, I m using the subroutine dflux for a simulation Abaqus Standard (coupled temp-disp). I would like to do this simulation in a dynamic Temp-disp Explicit step. I would like to know if it possible use the subroutine dflux in explicit. And what are the modifications i have do in dflux to...
