Predicting fracture energies and crack-tip fields of soft tough materials

Submitted by Teng zhang on

Soft materials including elastomers and gels are pervasive in biological systems and technological applications. Whereas it is known that intrinsic fracture energies of soft materials are relatively low, how the intrinsic fracture energy cooperates with mechanical dissipation in process zone to give high fracture toughness of soft materials is not well understood. In addition, it is still challenging to predict fracture energies and crack-tip strain fields of soft tough materials.

ABAQUS 6.14 FSI Engine Mapping Search Failure

Submitted by TU_61 on

I am doing a Co-Simulation in ABAQUS 6.14, where a fluid (water) flows through a Solid Steel. In my first trials, I used a Solid with one consistent hole, and a fluid. Everything worked perfect.
In my second trial the solid is wider and with two holes, so the fluid flows in one hole in and comes out at the other hole.

Journal Club Theme of September 2015: Kinematics of Crystal Elasto-Plasticity: F=FeFp

Submitted by celiareina on

This month’s blog focuses on one of the most common kinematic assumptions in the continuum mechanics of finite elasto-plasticity: the multiplicative decomposition . This expression decomposes multiplicatively the deformation gradient of the body  into to the elastic () and plastic () deformation tensors; and it will be discussed here in the context of dislocation mediated plastic deformations.
