摘要	Polymethyl methacrylate (PMMA) is one of important engineering materials and has been widely applied in various fields. Owing to the catastrophically brittle fracture nature, exploring the fracture mechanism of PMMA is of crucial significance to guide its engineering application. In this work, tensile tests with several kinds of sample geometries including unnotched samples and notch samples with different widths were designed to systematically investigate the macroscopic bifurcation of PMMA. Based on the sufficient experimental evidences, the traditional critical stress intensity criterion was found inappropriate for predicting the macroscopic bifurcation of PMMA. Finally, the fracture features were explicitly clarified based on the detailed experimental observations, and a new explanation to elucidate the fracture mechanism of PMMA was proposed.
