Abstract
The modeling and simulation of γ-graphyne under monotonic and hysteretic in-plane loading is presented. An atomistic finite element model of γ-graphyne was developed. Four different loading tests were conducted, including unidirectional tests in armchair and zigzag direction, bidirectional test and shear test. From monotonic analyses, the mechanical properties (elastic and strength) were obtained and validated. Hysteretic (cyclic) tests were performed to obtain stress–strain curves and the variation of dissipated energy with the number of cycles. The failure modes and the load-carrying capacity are analyzed. The proposed model simulates correctly the γ-graphyne monotonic and hysteretic mechanical behavior.
