Modeling of SMA in Patran and MSC.marc
I am doing my Masters degree,project is on
Shape memory alloy(NITINOL)......does any body know how to model SMA
using Patran and MSC.Marc?????

Is Your Thesis Hot? Or Not?
Writing a thesis about animal intentionality and tool use is
totally hot right now. A thesis about Robert Louis Stevenson's use of
the supernatural to symbolize evil? Not so much.
about the open source code for FEM
Hi, I am wondering whether there is any open source code for FEM for very simple cases. Thanks.
Help with curved specimen and mechanical loading
Background:
Rib fractures in infants are highly suggestive of child abuse. I am performing mechanical testing and finite element analysis on pig ribs with the aim of characterising the behaviour of ribs under anterior-posterior (from end to end rather from the side) loading.

Large electric field induced strains in ferroelectric islands
An effective mechanism that generates large recoverable electric field induced strains in ferroelectric islands is studied by phase-field modeling. The large strains originate from the reversible 90° domain switching between a1 (a2) domains and c domains, driven by an applied electric field and an internal stress field. The electric field induced strains could be effectively controlled by the magnitude of island-substrate misfit and the aspect ratio of islands.

Is peridynamics a superset of Continuum Mechanics?
Recently, I have found a new theory, called Peridynamics, used to solve, mainly, fracture mechanics problems in materials. But, I am confused about the issue if it is a superset of continuum mechanics or is it a totally new theory that reformulate our previous understanding of continuum mechanics? How do you measure material properties with this theory? Do we need to reformulate our theories to deal with fracture mechanics problems? Is it a totally accepted scientific theory?

transient analysis full method of ball bearing
i have to do transient analysis of ball beraing. but i could not get an appropiate tutorial to perform transient analysis using full method or mode superposition method since i cannot apply reduced method. please guide me how to apply the load step and what options to use.
I NEED HELP IN ANSYS ELECRTOMECHANICAL COU[PLING FOR SMART MATERIALS
Hi,I'm new to ANSYS. i'm working on project of active vibration control using piezoelectric patches using ANSYS .
But i'm finding it difficult in modeling of piezoelectric actuators and the input data required for it(VOLTAGE AND MATRIX).
Can any1 help me?i will be thankful
Multiscale method with model reduction
Model reduction based on Propper Orthogonal decomposition is widely used in Computational mechanics to reduce the number of degrees of freedom in systems. In the attached papers, we introduced a POD-based model reduction in a multiscale framework to significantly reduce the computations.
