Abstract This paper presents the calculation of complex stress intensity factors (K) for interface cracks in commonly used bi-material specimens subjected to arbitrary ununiform stress fields. First, detailed finite element analyses were carried out for cracks in centre-cracked plate (CCP) and single edge-cracked plate (SECP) bi-material specimens of

Stress-Intensity Factors and Complex Path-Independent Integrals
Journal of Applied Mechanics, 1980Path-independent integrals about crack tips may be used to estimate stress-intensity factors at crack tips in plane and antiplane elasticity problems. In this paper a new class of such integrals is established by using complex stress functions and the trivial application of the Cauchy theorem of complex analysis.

Mode-I stress intensity factors for cracked R-fluted shells under complex loads
International Journal of Pressure Vessels and Piping, 2021Abstract Based on the conservation law and bending theory, a technique to determine complicated stress intensity factors on three-dimensional components is proposed, A series of closed form expressions of stress intensity factor are derived for cracked shells under different loads, such as bending, tension.

A simple method for calculating the stress intensity factors for complex 3D cracks at a notch
Engineering Fracture Mechanics, 2016Abstract When performing a safety/durability assessment of structural components it is often necessary to consider both fatigue crack propagation and failure by fast fracture among the possible modes of failure. In this context the stress intensity factors at crack tips are important parameters for estimating residual life and criticality.

Description is given of a complex variable-variational method to investigate the stress intensity factor associated with the mode II cracking. In this work, a cracked plate is decomposed into two subregions with edge cracks. According to the theory of anisotropic elasticity the stress and displacement series which satisfy all basic equations and stress-

Abstract Thanks to the feature of being domain-independent for the interfaces with discontinuous mechanical properties, the domain-independent interaction integral (DII-integral) has become a quite effective method to solve the stress intensity factors (SIFs) of the materials with complex interfaces.
