In fatigue analysis, it is common to use S-N curve from database for spesific material, and some time for spesific way of loading. Is there any way to predict fatigue from direct simulation? For example, giving cyclic loading (10^5 times) and the material will suffer damage and eventually failed. In some FEM codes (MARC, LSDYNA, etc) there is Lemaitre-Chaboche model used to analyze material behavior under low cycle cyclic loading.
Thanks in advance

Global Strategies Group is looking for a Scientific Programmer to design, develop and implement software environment/components for geometry representation and mesh generation in support of computational mechanics applications
Significant software development/programming activity is expected.
Qualifications:
===============
Masters or PhD in Engineering or Computer Science
Background and experience:
==================================
I am developing an FEA code for a viscoelastic contact analysis. Right now the formulation is assuming small deformations. After deformation I am getting the volume of the body to be less than the original. I want to preserve the volume. ANSYS gives exact results as my code by carrying a normal contact analysis.
Using Computational Biology to Bring Predatory Dinosaurs Back to Life
The proposed programme of research seeks to use state-of-the-art computational techniques to reverse engineer the walking cycle of a predatory dinosaur. Software for image-based modelling, parallel finite element analysis and evolutionary robotics will be coupled and deployed
Our agency, Reliability Analysis Associates, Inc., specializes in recruiting Reliability Engineers and related skills. For a client in the oil business in Houston, TX we are seeking candidates for two positions that require knowlege of finite element analysis, crack growth, reliability, and low cycle fatigue. The two job descriptions are attached.
I noticed that the Rodney Hill Prize in Solid Mechanics has been founded and would like to have his personal records in detail, hopefully with his portrait(photo).
Simpleware Ltd. and COMSOL Inc. announced at the COMSOL Users Conference 2007 in Grenoble a partnership agreement to provide an export interface from Simpleware's world-leading 3D image-based meshing software +ScanFE™ to COMSOL Multiphysics® 3.4, the industry's foremost multiphysics simulation environment. The +ScanFE interface enables COMSOL users to directly import high-quality meshes generated from MRI, CT, and MicroCT scan data into COMSOL Multiphysics 3.4 for modelling and simulation without requiring re-meshing or pre-processing.
