Closed Form Expressions for Crack Mouth Displacements and Stress Intensity Factors for Chevron Notched Short Bar and Short Rod Specimens Based on Experimental Compliance Measurements

Series:

A set of equations are presented describing certain fracture mechanics parameters for chevron notch bar and rod specimens. They are developed by fitting compliance calibration data reported earlier. The equations present the various parameters in their most useful forms. The data encompass the entire range of the specimen geometries most commonly used. Their use will facilitate the testing and ana
