How to use the hybrid/mixed method to solve geometrical nonlinear problems?
It seems the the difficulties are how to choos strss(Cauchy, Lagrange or Kirchhoff ) and the corresponding expression of energy functional. When the large deformation is considered, the equilibrium equation is coupled with the displacements and the complementary energy is different with linear problems.
Coated nanoparticles, which have a core-shell structure, have many applications. The attached manuscript shows some of our progresses in investigating the induced torque and orientation of such nanoparticles in an electric field. We show that the shell of a nanoparticle has an important effect on its orientation, even when the shell is thin and takes only a small portion of the total volume. For instance, a thin layer coating of highly conductive Au can dramatically change the induced torque on a SiO2 or TiO2 nanoparticle.
Dear researchers,
I'm working with line cohesive interface element. It is been implemented in Fortran Code. I have some doubts about it.
The first one is: this element will be coupled with shell element, but as the line interface element doesn't have degrees of freedom of rotation this could cause some problems. Someone knows a formulation to line interface element that incorporate rotation in formulation?
Does any one knows a good reference about lath martensite?
Why we see the retained austenite? why doesn't it transformto martensite? What's its effect on the phase transformation? Does the plasticity change the morphology of the transfromation? How about the speed of the transfromation? When should we expect to see the lath martensite? What's the effect of the diagonal terms in the transformation matrix? What's the effect of the shear components? Is there any difference between 2d and 3d simulations, and which one is more realistic?

I am trying to use cohesive zone modeling for bimaterial fracture in ANSYS, but I have some problem while inputing the data. Can anybody suggest how to use cohesive zone modeling in ANSYS.
Hello,
Hi
I want to model an End Notched Flexure (ENF) specimen in ABAQUS for
studying the mode II fracture behaviour in laminated composites.
I have modeled the problem using shell elements and continuum shell
elements.
To prevent the two legs from penetration, I have examined almost all
of connector types (in ABAQUS/CAE) and also contact types but the
results have not been satisfactory.
