• Preliminary Wrapper software was assembled for coupoling ESI ACE+ with MesoEqs

​

  • ACE+ software by ESI-Group has an extended multi-physics capability and represents many existing commercial engineering design and analysis tools

​

  • A fundamental challenge in coupling FEM software with MesoEqs was addressed that is the inherent discrepancy between the finite length scale in the peridynamic model (the horizon) and the zero-length scale of the standard FEM local model

​

  • This challenge was addressed using so-called peridynamic partial stress approach introduced by Sandia National Laboratories

​

  • MesoEqs Wrapper was demonstrated for a bar under tension problem

​

  • Here, a bar was discretized into five domains: full peridynamics at the center peridynamic partial stress regions between FEM (ACE+) and meshfree peridynamics domains, and classical continuum mechanics regions at the ends of the bar

​

  • Smooth transitions between solutions obtained using FEM, Partial Stress, and Peridynamics were observed, which validate the developed MesoEqs Wrapper
