Abstract: (623 Views)
Analyzing and modeling damage and crack growth in bodies and structures is one of the important issues in designing methods to prevent crack growth or stop it in order to avoid sudden fracture and increase the lifetime of structures. Extensive research has been performed in the field of modeling fracture, crack growth, and damage in bodies and structures. However, there are still many problems in modeling crack growth and damage in bodies with points of singularity and discontinuities. In recent years, a new theory called peridynamic has been proposed to model and analyze such problems. The formulation framework of peridynamic theory is based on integral equations. In addition, points of singularity and discontinuities and damage in the body and modeling them are another type of deformation and part of the structural equations of this theory. As a result, the peridynamic theory is used directly, without the need for additional relations to model crack growth in problems involving points of singularity and discontinuities. In this paper, a bond-based peridynamic modeling for unidirectional carbon fiber reinforced polymer material(UDCFRP) 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 crack and damages in UD-CFRP machining.
