Fracture Toughness of Stretched Acrylic Plastic

CODEN: JTEVAB

Abstract

This paper presents the method and results of a parametric study of instability toughness, as measured by the plane-strain KIc and plane-stress Kc fracture toughness of a multiaxially stretched acrylic plastic. A large number of computer-controlled tests were conducted with the compact tension specimen under high compliance loading/load control. These tests reveal the significant effects on Kc and KIc of a wide range of loading rates, specimen thicknesses, and specimen geometry. A direct and immediate application of the results is the recommendation of a new fracture toughness acceptance test for these materials.
