摘要：

This paper presents the first attempt to investigate the fracture behavior of functionally graded multilayer nanocomposite strip reinforced with a low content of graphene platelets (GPLs) whose weight fraction is gradually changed in the thickness direction according to different non-uniform and uniform distribution patterns. Based on the transfer matrix method and Fourier integral transform technique, the governing equations of a multi-layered model of the GPL reinforced functionally graded strip are derived within the framework of elasticity theory which are then transformed to Cauchy singular integral equations. Both mode I and mode II stress intensity factors (SIFs) of a parallel interface crack embedded in a functionally graded GPL-reinforced composite (FG-GPLRC) strip are solved numerically by using the linear multi-layered (LML) fracture model. A detailed parametric study is carried out to investigate the effects of the distribution pattern, weight fraction, geometry and size of GPL nanofillers as well as crack location on the fracture behaviors of the FG-GPLRC strip.
