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

tensor
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?
Strain softening behavior
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
Back Stress in Abaqus
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.

Theory of dielectric elastomers
In response to a stimulus, a soft material deforms, and the deformation provides a function. We call such a material a soft active material (SAM). This review focuses on one class of soft active materials: dielectric elastomers. Subject to a voltage, a membrane of a dielectric elastomer reduces thickness and expands area, possibly straining over 100%. The phenomenon is being developed as transducers for broad applications, including soft robots, adaptive optics, Braille displays, and electric generators.
Amplitude with ABAQUS.
Hi friends,
I am using ABAQUS to model a O-Cell load test for deep pile foundation. I would like to applied the load which gradually increases with time (in second). But, if I apply the load step by step then it may take much time to input the data. I think we can use AMPLITUDE toolset in ABAQUS to define the incresing load (ex.), but I don't know how to apply the load by using AMPLITUDE toolset.
Example I have:
Time(sec) --- Load (kN)
1--- 100
15 ----500
30----1000
etc..
State of hydrostatic stress along shear zone.
Dear all,
I did a three point bending test on a brittle rod. I observed an oblique fracture (slant approx 45 degrees). It can be an easy conclusion that this 45 deg crack is due to shear failure. But i have the following questions
1. Can a shear band occur in bending mode? as in literature very frequently shear bands are reported in pure tension and compression.
