Backstress in Material Ratchetting
Dear All,I am studying cyclic loading, Plasticity and metal ratchetting. All the publication related to these topics mention about backstress. Please somebody explain me what is the backstress. Could you please suggest me a reference to learn fundamentals?bandula
Cannot see result summary at ansys
Hi, everyone ,,,I am a new user using ansys, i am working with pipe model. I build my pipe with solid 42 and solid 45 and meshing it. However,after running it, I cant see the result summary at POST1 even in the output window the result showed. Any one have a problem like this? if yes..how to solve it ,,,thanks
Inelastic hosts as electrodes for high-capacity lithium-ion batteries
Silicon can host a large amount of lithium, making it a promising electrode for high-capacity lithium-ion batteries. Upon absorbing lithium, silicon swells several times its volume; the deformation often induces large stresses and pulverizes silicon.

dracker prager plasticity model with softening
Hi my friends,i am using Dracker prager plasticity model to simulate uniaxial compression (softening) of coal samples.in dracker prager, the shear criterion is linear, and the hardening type is compression. there is a table that i should fill out, this table composed of yield stress and abs. plastic stain. my question is:- how can i fill out this table by using the experimental data (stress-strain diagram for uniaxial compression test) ?? shall i convert these data using any equations??
Beam on elastic foundation
Dear All,
I am wondering that is there any closed form solution for beam on elastic foundation in case which we have got two stiffness for the springs namely (axial and shear stiffness). The axial force are born because of the some loading conditions in the support.Would you please help me about this?
Thank you,
Parisa
Strain stiffening induced by molecular motors in active crosslinked biopolymer networks
We have studied the elastic response of actin networks with both compliant and rigid crosslinks by modeling molecular motors as force dipoles. Our finite element simulations show that for compliant crosslinkers such as filamin A, the network can be stiffened by two orders of magnitude while stiffening achieved with incompliant linkers such as scruin is significantly smaller, typically a factor of two, in excellent agreement with recent experiments.
