    Static Analysis

    Dear How to solve this problem of convergence in ABAQUS (The analysis has been terminated due to previous errors. All output requests have been written for the last converged increment. Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if...

    How to model Hashin 3D-and Puck damage for composite in Abaqus using the implementation with UMAT ?

    Dear I want to develop HASHIN and PUCK damage initiation and progressive damage with gradual degradation material properties(energy based) in composites with continuum elements (3D stress) with UMAT subroutine and delamination with damage initiation and progressive damage of cohesive element...

    Repeated impact in composite plate

    FEA way now it works well, but without the cohesive elements between the layers. so my last question,in cohesive zone model, i know one method that define properties in the interaction modules but in results we can't see the interface of delamination ,my question how i define the properties in...

    Repeated impact in composite plate

    Mustaine3, where i find contact exclusion , i didn't find it in the interface of Abaqus

    Repeated impact in composite plate

    FEA way ,thanks ,i do it but the problem between the impactors so for example when the first impactor rebound ,dont permit to the second for impacting the area ,and he toped the second impactor

    Repeated impact in composite plate

    FEA way and Mustaine3 Thanks for your answers ,i will use the second approach ,to model various impactor ,if each impactor i will specify the step ,so multi-steps ? on the other hand how i calculate the interval between impactors ?

    Repeated impact in composite plate

    thread799-343531 Hello I have a problem about the simulation of progressive damage in composite plate under repeated (multi-impact) low velocity impact using soubroutine Vumat implimented in Abaqus ,I was developped the soubroutine and i validate with experemental data with different...
