Numerical analysis of quasi-static fracture in functionally graded materials
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.

Determination of stress intensity factor of FGM materials
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.

Composite Manufacturing Process Modeling Using Poromechanics
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.
