Stress Analysis of Rectangular Plate With Bilateral Interface Cracks Under Hybrid Boundary Conditions
Presented is an approach for obtaining whole-field stress distributions of a bi-material rectangular plate, which is composed of plate I and plate II with a fixed boundary and subjected to external loads, using elasticity mechanics theory. There are two cracks at the edges of the interface of plate I and plate II, which are called as bilateral interface cracks. In the analysis, the effects of the ratio of Young’s modulus of material I (plate I) and to that of material II (plate II) and the ratio of the crack length to the width of the plate on the stress distributions in the vicinity of the interface were examined. Stress Intensity Factor (SIF) and normalized SIF equations were also calculated through the stresses in the vicinity of the crack tips.
