Arguments for Drucker Prager creep model with user defined law??

Submitted by sud1986 on
research

Hey all,

I am trying to use Drucker Prager plasticity with Tension hardening model for my material in Abaqus. In addition, I want to use the Drucker Prager creep with user defined (user) law that is via creep subroutine. But when I try to choose the Drucker Prager creep in the Abaqus CAE, it gives an error, "not all required arguments specified; expected 1, got 0." I am not able to follow what arguments it is asking for when I am using a user defined law. Any help regarding the same will be greatly appreciated. Thank you.

ABAQUS/CAE

Hi every one . I am working on Simulation of precision glass molding process with the help of  Abaqus . Do any one have idea to simulate the glass at temprature 1400oC ? Please send me any usefull material regarding it.

Kind Regards

Analysis of microstructural induced enhancement of electromechanical coupling in soft dielectrics

Electroactive soft elastomers require huge electric field for a meaningful actuation. We demonstrate, by means of numerical simulation, that this can be dramatically reduced and large deformations can be achieved with suitably designed heterogeneous actuators. The mechanism by which the enhancement is attained is illustrated with the aid of both idealized and periodic models.

In today's (May 2) issue of Nature, we report a recent achievement in applying mechanics principles of stretchable electronics and optics to create biologically inspired artificial compound eye cameras. It was also highlighted in the Nature News & Views, "Optical devices: Seeing the world through an insect's eyes".
