## 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

The interaction between a macroscopic crack and microscopic, continuously distributed, damage is studied both for time-independent and time-dependent damage formation. This damage is a measure of an assumed continuous deterioration of the material. A thin cracked sheet loaded in mode I is considered
A nonlinear finite element analysis, based on the incremental theory of plasticity with isotropic hardening rule, has been performed for the process of slow crack growth in center-cracked specimens made of 2024-T3 aluminum alloy. With experimental data relating the applied stress and the crack size
