Study on fracture process zone near mode II and mode III dynamic crack tip
Arabian Journal of Geosciences, 2020Determination of the configuration and size of fracture process zone (FPZ) at dynamic crack tip is still a problem unsolved completely at present. In this paper, based on elastic dynamic theory and stress functions, a method for evaluating the configuration and the size of FPZ is proposed and the feasibility of the method is demonstrated.

Near-threshold propagation of mode II and mode III fatigue cracks in ferrite and austenite
Acta Materialia, 2013Abstract The near-threshold behavior of mode II and mode III long fatigue cracks in ferritic (ARMCO iron) and austenitic (X5CrNi18-10) steel were experimentally studied using various samples specially prepared to obtain the effective threshold values ΔKIIeff,th and ΔKIIIeff,th.

K-calibration of special specimens for mode II, III and II+III crack growth
Engineering Fracture Mechanics, 2013Abstract An original testing setup has been designed for generating pure remote mode II, III and mixed mode II + III crack propagation in a single cylindrical specimen with circumferential crack. This specimen is currently used for investigations of a shear mode fatigue crack propagation. The aim of this work was to perform the K-calibration of above

Abstract This paper deals with mode III and mixed mode (III + II) delamination behavior of woven glass fiber reinforced polymer laminates; numerically and experimentally. An improved test method was employed to study fracture under pure out of plane shear condition (mode III) using edge crack torsion (ECT) specimen. Load–displacement curves indicated

International Journal of Fatigue, 2016
Abstract The paper is focused on an identification of the local mode II mechanism of fatigue cracks loaded under the remote mode III and the mixed mode II + III and presents a convincing experimental evidence of such a mechanism in materials with a nearly coplanar crack growth.

Journal of Failure Analysis and Prevention, 2020
Stress intensity factor (SIF) of surface cracks (semi-circular, semi-elliptical, and irregular shapes) located on a circular pipe (hollow) has been determined using numerical method. The irregular-shaped crack geometry was considered in the present work in order to simulate the cracks that are generally developed during service condition.

Straightforward comparison of fatigue crack growth under modes II and III
International Journal of Fatigue, 2008Low-cycle fatigue crack propagation in double circumferentially notched, cylindrical specimens of austenitic steel was studied by means of special testing device in order to identify local fracture micromechanisms under remote shear modes II and III. Remote mode II crack growth rate was found to be approximately two times higher than that of the mode ...

Investigation on mixed-mode II-III fracture of the sandstone by using eccentric cracked disk
Theoretical and Applied Fracture Mechanics, 2021Abstract Most of the fractures in deep rock mass are in compression condition. The deep rock failure is complex and different modes of failure play important roles. In this study, the central cracked circular disk specimen was improved by deviating from the distance between the crack on the circular surface and the center of the circle, and a new ...
