Elasto-Plastic Analysis of metal component with Cyclic Loading

fatigue analysis

Hi,

I am pursuing my master's in Mech. Engg. and working on Abaqus for FEA of components. In one of the analysis,

I am required to apply cyclic loading on the component to determine the Stresses at the edges. Its a compression

cyclic loading with kinematic hardening taken into account. From the documentation for ABAQUS 6.9.1, I found that

in order to apply kinematic hardening in metals, one must take it as Combined (Isotropic + Kinematic) Hardening.

The two concerns I have about this analysis are:

Nonlinear problem

numerical continuation

Hi!

I am trying to solve (for equilibrium points) a geometrically nonlinear problem of the form

f(u) = F

where u is the displacement and F is the load. At first I tried the plain

Newton method, with, perhaps obviously, limited success. I then tried to use

linesearch and trustregion strategies to improve the situation. Eventually, however,

I realized that I needed to use some form of continuation method. Though the most

commonly used methods in mechanics seems to be based on gradually increasing the

Micro-sphere Model

Submitted by Joachim Guilie on Thu, 06/17/2010 - 18:51

Hi all,

I am currently working on micro-sphere model like the one used by Miehe, Ihlemann and Pawleski. I wonder if someone know a FEM code who use this type of model.

Thanks a lot

cantilever beam

i want to create a crack in a cantilever beam, but i m new in this field. please tell me how to model a crack in beam when beam is meshed using 1) beam elements 2) solid elements?

please refer any good tutorials in this field.

carpal tunnel syndrome

1. We present an interesting application of ADINA FSI in the study of carpal tunnel syndrome. The analyses involve large deformations and contact of multiple flexible bodies which are immersed in a fluid:

Geometric Nonlinear Finite Element Program

Submitted by chenjinghao on Sun, 06/13/2010 - 02:17

I'm programming a finite element program to analyze the force of submarine pipeline.When the pipeline is lifted highly from seabed，it is a large deformation problem.

Is there any open soure to solve the problem?

Give me some advices.

Thanks a lot!
