Hello everybody
I try brain injury in abaqus 6.13. I use for 3d modelling mimics software and 3 matic. ı make all brain parts from MRI in mimics and export to 3 matic for meshing. I do smoothing,reducing triangle etc. in 3 matic. then export to abaqus with orphanmesh. ı am doing assmbly, step, intreaction, bc,jop etc. in abaqus and run. ı use just abaqus interface but not phton ı am new in abaquse. my problem are

This work investigates the existing capabilities and limitations in numerical modeling of fracture problems in functionally graded materials (FGMs) by means of the well-known finite element code ABAQUS. Quasi-static crack initiation and growth in planar FGMs is evaluated. Computational results of fracture parameters are compared to experimental results and good agreement is obtained. The importance of the numerical fit of the elastic properties in the FE model is analyzed in depth by means of a sensitivity study and a novel method is presented.
At this stage, the entire wooden flooring and other home made popular home industry, but not all enterprises can take the entire wooden home this road development, the entire wooden home is the need to have the strength in all aspects of business, such as information dissemination, quality and environmental the major issues and problems, such as sales channels still bring a lot to the floor challenging.

We have openings for new PhD students in the Biomimetic Materials Laboratory at McGill University, starting January 2015.
It is important to note that the determination of Stress intensity Factors lead to major problem for researchers, some of them have proposed an analytical method based on linear fracture mechanic by using the theorem de Giffth and also Paris, other have proposed numerical method using finite elememt analysis codes such as Ansys or Abaqus, other researcher have used experimental method.
However, these methods still need an improvement for given accurate results.
How to develop an analytical method and adopted to FGM structure.

Modeling and simulation of manufacturing of advanced composite material is a must in today's industry as the use of advance composites is increasing dramatically. The aim is to reduce the number of trial and error by development of a simulation tool to model and predict the manufacturing fundamental phenomena happening simultaneously in different scales. Poromechanics is a multidisciplinary and multiphysics concept which can be used to achieve this goal.
A 3D constitutive model is proposed and verified with experimental data. Tension-torsion coupling effect and tension-compression asymmetry effect is investigate for tube shape memory alloy.
