Numerical Determination of Crack Opening and Closure Stress Intensity Factors

The aim of the present work is to evaluate the quasi-static behavior of the shaft (displacements and opening of the crack) at different angular positions of the rotation.

In the present work, stress intensity factors are determined for an inclined crack in a finite or- thotropic lamina subjected to uniaxial / biaxial loading to study the effect of

In this paper, the behavior of the crack growth, the fatigue life of U-shape specimens under different level of loadings and the determination of the sheet thickness on the

The values of non-dimensional stress intensity factors for pure mode-I, pure mode-II, and pure mode-III were obtained using 3D models of new loading device and modified Arcan

In this case, oxide-induced crack closure (Figure 7), roughness-induced crack closure (Figures 6 and 8) and crack deflection (Figure 6) are together the causes of 50%

Although additional experi- mental and numerical studies appear necessary to establish a more definite methodology for fatigue life predictions including crack closure

Strong discontinuity models simulate the relation between forces through the crack and the opening of the crack (discontinuity of the internal displacement field of the element).

However, cluster analysis, without considering the space, allowed the identification of some localities that also present this contradictory dynamics, especially in
