New release of Abaqus2Matlab: GUI, reading .odb and much more!

A2M GUI interface 

Dear imechanicians,

A new version of Abaqus2Matlab has just been released and I hope that it is of interest to you.

This new release constitutes a very significant step forward in the development of this well-known software to connect Abaqus and Matlab.

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.
