Fatigue cracks in shot-peened and case-hardened notched machine components are subjected to stress fields induced by the external load and residual stresses resulting from the surface treatment. Both stress fields are characterized by nonuniform distributions, and handbook stress intensity factor solutions are in such cases unavailable, especially in ...

Abstract The recently developed complex Taylor series expansion method for computing weight functions (WCTSE) of arbitrary 2D crack geometry is further studied. Improvements on several aspects are made to raise solution accuracy. Wide-range weight functions are determined for four different crack geometries.

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.

Fatigue & Fracture of Engineering Materials & Structures, 2004
ABSTRACTLinear elastic fracture mechanics (LEFM) is the science frequently used to understand the stable and progressive fatigue crack growth that often occurs in engineering components under varying applied stress. The stress intensity factor (SIF) is its basis and describes the stress state at the crack tip.

In the present paper, the closed-form expressions for the stress intensity factors (SIFs) and the elastic crack opening displacements (CODs) of complex-cracked pipes are derived based on the systematic three-dimensional (3D) elastic finite-element (FE) analyses. The loading conditions that are evaluated include global bending moment, axial tension, and

Abstract A finite element computer program EPAS-J1 was developed to calculate the stress intensity factors of three-dimensional cracks. In this program, the stress intensity factor is determined by the virtual crack extension method together with the distorted elements allocated along the crack front. The program also includes the connection elements

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.

Evaluation of a Complex Stress Intensity Factor of Interface Cracks: A Perturbation Approach
Journal of Applied Mechanics, 1993The complex stress intensity factors are evaluated for a crack located on a bimaterial interface. The oscillatory index \(\varepsilon\) is treated as a small parameter of the problem. Two cases are considered: 1) a semi- infinite crack loaded by a distributed traction along the crack boundary, 2) a finite crack with tractions prescribed on its surface.

AbstractIn this article, the boundary element method is implemented for solving linear elastic fracture mechanics problems, using new complex Fourier shape functions which include constant and linear complex Fourier shape functions. They, unlike the classic Lagrange shape functions, can satisfy the exponential and trigonometric function fields in ...
