A contact algorithm for frictional crack propagation with the extended finite element method
contact algorithm frictional crack extended finite element method
2015/7/1
We present an incremental quasi-static contact algorithm for path-dependent frictional crack propagation in the framework of the extended finite element (FE) method. The discrete formulation allows fo...
A Synergistic Approach to Modeling Crack Propagation in Nanoreinforced Polymer Composites
Modeling Crack Propagation Nano Reinforced Polymer Composites
2014/10/23
Empirical studies indicate that a polymer reinforced with micro- and nano-scale particles could enhance both the stiffness and toughness of the composite. In addition to these augmented attributes, th...
