Damage prediction in graphene thermoplastics for potential electronic packaging applications

Abstract

Graphene is a promising material for electronics industry due to its unique mechanical and electronic properties. In this study, the failure analysis of the graphene sheets is performed by using Peridynamic theory due to its unique capability in failure prediction at the continuum level and the similarity of its mathematical structure to the molecular dynamic simulations (MDS). The current approach is validated against MDS predictions by considering zig-zag and armchair type single layer graphene sheets with an initial edge notch subjected to tension loading. Finally, a similar analysis is performed for multi-layered graphene layers which are either commensurate or incommensurate to investigate the effect of number of zigzag and armchair type graphene sheets and their stacking sequence on failure modes.
