Dear all
When i assign the springs between pair points in two
plate over each other, the spring definitely acts in one direction only
(perpendicular to the plates), but they must be assigned in such a way
that the springs work in three orthogonal directions. it is important to
mention that the two plate is fastened using screws, where the spring
has been used for screw.
how can i overcome this problem?
Best Regards
can i use the equivalent plastic strain to evalute the state of the elements (yield or elastic) when the i use Mohr-Coloumb plasticity (Abaqus 6.6).
i am asking this question because i made a model to simulate the uniaxial compression test using mohr-coloumb plasticity, but i find that the equivalent plastic strain remain constant at all elements, i am sure that the it should change from the edged of the sample to the core of the sample.
Dear colleagues,
There are only five days left to submit an abstract to 2011 MRS Spring
Meeting, and we call contributions from mechanics community to Symposium Z: Nanoscale Electromechanics of Inorganic,
Macromolecular, and Biological System. More information about the symposium, including a list of invited speakers, can be found at

hi my friends, i am new in Abaqus, while i am making a uniaxial compression test for coal sample using Abaqus 6.6, the failure criteria is Mohr-coloumb plasticity, i know that the behavior of coal is strain softening. i should use this table to simulate the hardening/softening behavior of material.

Hii all,
Is it needed to assign singular elements in VCCT technique.
Thank You
