Abstract
This second paper of the two-paper series describes a comprehensive experimental verification of the response of the Rigid-Insert Crack Closure Model (RICC) and the related CMOD-Compliance Closure Assessment Technique (CCCA) to variations in the material elastic properties, crack surface roughness, specimen dimensions, crack size, and loading conditions. The experimental procedures are particularly designed to ensure a “uniform” K- increasing crack wake which provides consistent crack closure data. The experiments are performed using two different materials, two selections of specimen sizes, at different crack lengths and stress intensity factors.
