## Abstract Slow crack growth in Perspex acrylic sheet (PMMA) and Simplex acrylic bone cement in air and water has been studied from a fracture mechanics viewpoint. It has been found that the crack velocity, __V__, for each material depends upon the intensification of stress at the tip of the crack

finite element analysis of the process of slow crack growth is made for center-cracked specimens subjected to monotonically increasing load until the point of fast fracture is reached. The formulation is based on an incremental theory of plasticity with isotropic hardening. Numerical results and exp
## Absfraet -Brittle material fractures at a critical value of stress intensity factor or crack opening displacement (COD) without any prior crack growth. In the ductlk materials, however unstable fracture initiation may be preceded by a period of slow crack growth from the notch tip. Such slow cr
The potential drop method as used in fatigue and fracture toughness testing has been applied to tests on COD specimens. These tests showed that providing electrical stability is maintained, the method can be used to detect the onset of ductile crack growth. Initial plastic deformation (in absence of
An ethylene-hexene copolymer was fractionated into five fractions and the density of shortchain branches was measured for each fraction. The slow crack growth behavior was measured on each fraction by sandwiching the small amount of fractionated resin of about 0.2 g between polyethylene grips. The r
