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

Experimental Investigation of Modes II and III Fatigue Crack Growth in Unalloyed Titanium
Key Engineering Materials, 2013The study is focused on finding and describing microscopic paths of modes II and III cracks in commercially pure α-titanium (hcp structure). Experiments were done on cylindrical bars with a circumferential cracked notch loaded in shear (modes II, III and II + III) and torsion (mode III).

Main crack-microcrack interaction under mode I, II and III loadings: Shielding and amplification
International Journal of Mechanical Sciences, 1991Abstract This article examines the effect of the presence of a general microcrack upon the stress intensity factor at a main crack KMA under the influence of independent mode I, II or III loading. Specifically, it is desired to obtain the different contour levels corresponding to the regions where KMAI, KMAII and KMAIII (shielding effect) or ...

Abstract Using the results presented in Part I, together with various criteria, we try to explain qualitatively and quantitatively crack front rotation and segmentation under mixed mode I+III or I+II+III conditions. We first give a qualitative explanation of segmentation in mode I+III, based on the energetic theory of fracture.

Study on Fracture Prediction for Cracks Under Mode II and III Loading Combined With Mode I
Volume 1: Offshore Technology; Structures, Safety and Reliability; Materials TechnologyAbstract Predicting brittle fractures in beam-to-column connections under mixed-mode loading remains a significant challenge in structural engineering. Traditional approaches predominantlyy focus on mode I crack opening, often neglecting the contributions of modes II and III.

A numerical analysis by means of the ANSYS code was performed in order to identify the ratio of both stress intensity factors and crack tip opening displacements for a cylindrical specimen with circumferential V-notch loaded by remote pure shear stress.

The topography of the core-region around cracks under modes I, II and III of fracture
International Journal of Mechanical Sciences, 1983Abstract The core region, defined as the limiting zone of validity of the various brittle fracture criteria, has been intuitively assumed as a circle. Its experimental determination is based here on a simple asymptotic elastic theory and a verification by the method of reflected caustics.

Three-dimensional crack initiation mechanisms in bcc-Fe under loading modes I, II and III
Materials Science and Engineering: A, 2013Abstract We present quasicontinuum simulations of three-dimensional (3D) edge cracks in single crystal bcc-Fe. Crystals with different thicknesses and crystallographic orientations have been investigated and loaded in modes I, II and III. We study incipient plasticity at the crack tip and the onset of crack propagation, and calculate the critical ...

A penny-shaped crack in a transversely isotropic piezoelectric solid: Modes II and III problems
Acta Mechanica Sinica, 1999An exact analysis of the modes II and III problems of a pennyshaped crack in a transversely isotropic piezoelectric medium is performed in this paper. The potential theory method is employed based on the general solution of three-dimensional piezoelasticity and the four harmonics involved are represented by one complex potential.
