This mini symposium is aimed towards providing fruitful discussions and exchange of ideas and concepts among different approaches used by researchers in the field of interface evolution under possible dynamic conditions. Several mechanical problems fall into this category, amongst which are dynamic crack propagation, fluid-structure interaction, wave propagation and fluid interface tracking. Furthermore, contact Mechanics is one of the most growing research fields in Mechanics. This Mini-Symposium aims at providing a forum for specialists in fracture mechanics and contact mechanics to discuss advances in mathematical formulations and computational models for interface mechanical problems in the Partition of Unity framework with possible dynamic loadings. Within this area different aspects have to be considered. Among them are new discretization techniques, multiscale approaches ranging from the macro to the nanoscale, robust and innovative solution schemes. The topics of interest are wide ranging. The basic list of the main pertinent subjects includes: 

  • discretization techniques and Constraints enforcement methods in the Partition of Unity framework;
  • contact detection algorithms;
  • friction, adhesion, debonding, delamination and failure processes;
  • coupled multifield problems;
  • computational efficiency of the solution procedures;
  • multi-scale approaches;
  • contact at the nanoscale, roughness of contact and fracture surfaces;
  • cohesive zone models for decohesion and contact at interfaces;
  • interface problems in multi-physics, multi- material systems;
  • interface problems in composites and in polycrystalline materials;
  • fracture mechanics with contact (fretting or rolling contact fatigue,…) ;
  • X-FEM, G-FEM and other partition of unity based methods;
  • Meshfree  methods such as SPH and EFG;
  • Embedded finite element methods;
  • Fictitious domain methods. 

Perspective Authors are invited to present innovative analytical and numerical methods based on dynamic fracture mechanics or / and contact mechanics for the characterization of the mechanical behavior of interfaces in engineering applications, for discussing the most recent advances and the perspectives for future developments in this area.
