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

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.
