Abstract
The role of the breadth of isochromatic fringe loops in the multi-parameter method of analysis for determining mode-1 stress intensity factors,K1, is investigated. Static and dynamic photoelastic isochromatic crack-tip fringe patterns associated with cracks in Single-Edge-Notched, Modified-Compact-Tension, and Rectangular-Double-Cantilever-Beam fracture test specimens are analyzed. Three measurement quantities, the apogee distance, the tilt angle and the breadth of one isochromatic fringe loop are used to determine the stress intnsity factorK1 and the first two higher order terms in the stress function expansion. It is known, that the breadth of an isochromatic fringe loop is mainly controlled by the first two higher order terms.
