crack propagation in Abaqus (VCCT) with remeshing

I started using VCCT with quarter tip elements in Abaqus (not XFEM). I can solve the problem and get the SIFs.
How can I let the crack grow? Has someone a script for crack growth and remeshing that I can implement?

Postdoc Position in Computational Modeling of Growth and Remodeling Mechanisms

A postdoctoral fellowship position is available at the laboratory of Rafael Grytz, PhD, at the University of Alabama at Birmingham, for 2 years, starting immediately. The candidate will be instrumental in developing computational methods to quantify and simulate growth and remodeling mechanisms in ocular conditions and diseases.

Non-linear multiphysics modeling of ionic gels

The paper presents a thermodynamically consistent modeling of the non-linear multiphysics of ionic polymer gels based on the multiplicative decomposition of the deformation gradient. In particular, the deformations induced by the motion of ions under an applied voltage are viewed as distortions, similarly to growth-induced deformations in soft tissues. Furthermore, a consistent linearization of the model in the regime of small deformations is discussed. Finally, a finite element implementation of the theory is introduced and validated against experimental results.

Call for special issue papers: Mechanics of cells, tissues, and biomaterials

The paramount role of mechanics in life has recently been the center of attention of many researchers. This special issue will be focusing on the role of mechanics in the life of cells and tissues and their interactions with biomaterials. Original research and review papers are solicited for review and publication in the journal Mechanical Sciences . Mechanical Sciences is an academic open-access journal sponsored by the Library of Delft University of Technology and The Netherlands Organization for Scientific Research (NWO).

Journal Club Theme of January 2012: Mechanics of Growth

"I can't understand how people are still working on growth. That stuff's all done." This was the beginning of the first lunch conversation at a recent Banff workshop on Mathematical Foundations on Mechanical Biology... somewhat frustrating for someone who is excited about growth. Fortunately, most of the presentations and discussions still focused on growth. Although "that stuff's all done".

van der Waals interaction controls orientations of single-walled carbon nanotubes on quartz during growth

Single-walled carbon nanotubes (SWNTs) possess extraordinary electrical and mechanical properties, with many possible applications in electronics and materials science. Dense, horizonally aligned arrays of linearly configured SWNTs represent perhaps the most attractive and scalable way to implement this class of nanomaterial in practical systems. Recent work shows that templated growth of tubes on certain crystalline substrates (e.g. quartz) yields arrays with the necessary levels of perfection, as demonstrated by the formation of devices and full systems on quartz.
