Modified Residual Property Model For Fracture Mechanics

In this paper, the application requirement of Residual Property Model based on decrescent exponential function is reduced to only one mechanical test data. For this, by using Creager and Paris's elastic stress field equation in front blunt elliptical hole, theoretical radius was chosen for tip curvative maximum load direction at ensured be equal fracture toughness. Thus, workload model making u exponent e-u dependent geometric correction factor crack length. It applied laminated composite specimens with three-point bending including circular critical values close actual were achieved.
