    creep/plasticity algorithm

    Hi, First of all i want to thank you for your interest. i tried everything you suggested. i would like to inform you about the results. C3D20 elements achieve better convergence but still the second step of the analysis is not completed. Also i have read that this type of element shouldn't be...

    creep/plasticity algorithm

    hi i have tried to use quadratic elements but still the creep algorithm does not converge. the first increment converges. in fact the first step is completed successfully. i am using strain hardening model in drucker prager card of Abaqus. Thanks for your concern svufer

    creep/plasticity algorithm

    Hi I have a 3d model that consists of 3 parts with 3 different materials. One is elastic the second porous elastic and the last one drucker-prager linear hardening (shear). the element type i use is C3D8.the solution does not converge and the exact warning message is creep/plasticity algorithm...
