A bond-based peridynamic modeling of machining of unidirectional carbon fiber reinforced polymer material

As an alternative theory of solid mechanics, the peridynamic theory is an effective method to analyze the damage process of materials. In this paper, a bond-based peridynamic modeling for unidirectional carbon fiber reinforced polymer material(UD-CFRP) orthogonal cutting process is proposed, and the corresponding composite material bond failure criterion is also investigated for better revealing the machining mechanism of UD-CFRP machining. From comparing between simulation and experimental results, it can be indicated that the peridynamic modeling is capable for predicting the chip formation and surface damages in UD-CFRP machining. The investigation about effect of critical stretch and mass density on the machined surface crack is also conducted.
