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.

The international conference "Syntactic and Composite Foams III" will be held in Cetraro (Italy) May 29th - June 3rd, 2011. Abstracts of approximately 300 words should be submitted no later than January 15th, 2011 for oral presentations and March 1st, 2011 for poster presentations.

Hii all,
Is it needed to assign singular elements in VCCT technique.
Thank You
It's not to late to register and attend upcoming Abaqus Regional Users' Meetings hosted by
SIMULIA. Check out the upcoming RUMs in locations such as Michigan, Japan, Spain and 16 additoinal locations around the world.
Register online to attend in order to gather simulation tips and techniques from your peers and learn about the latest FEA, Multiphysics, Optimizatoin, and SLM capabilities from SIMULIA.

Respected Sir,
I want to know the answer of following questions
1) what is tensor?need of it? & its physical signjficance?
2)what is the psocedure to write high order tensor in matrix form?
3)is there any general formula to calculate no. of independent variable in tensor for any dimension?
hi my friends, i am new in abaqus, i want to use Mohr-Couloumb plasticity to simulate the uniaxial compression of a coal sample, the behavior of coal is stain softening, i want to know how many data points should i use in the hardening menu of Mohr-coloumb plasticity (cohesion yeild stress & Absolute plastic strain ).
you know that the strain sofening bhavior has yield point and peak and then post peak (softening).
when i make the simulation i used 3 data points
Could you please advise if that is correct to select higher number of back stresses (as input) while simulating test results in Abaqus?
It appears to me that the higher number of back stresses (say selecting number of back stresseses in Abaqus >= 5) give me a better fit to the test results. For my case, 5 is an optimal value as increasing it will not affect the results, much.
Thank you.
