Mixed Mode Fracture of Brickwork Masonry

2008
The brickwork masonry, especially walls, often shows cracking ought to differential settlements and excessive deflections of the slabs. In these circumstances the cracks are induced by a combination of tensile and shear stresses, under static loading.

An experimental investigation of mixed-mode fracture

International Journal of Fracture, 1989
In this paper, mixed-mode fracture is investigated experimentally. In the first part, critical conditions for initiation of crack growth are explored. The method of caustics was used in conjunction with a high speed video system to determine critical stress intensity factors at initiation of crack growth. It was found that the maximum tangential stress

Mixed Mode Fracture in Electronic Packages

MRS Proceedings, 1996
AbstractIn this paper, mixedmode (mode I + mode II) fracture toughness data are presented for the prediction of molding compound (silica filled epoxy resin) failure. The stresses necessary to cause the package cracking under mixed mode loading are experimentally determined.

On mixed-mode fracture of PVC foam

International Journal of Fracture, 1998
This paper reports on mixed-mode fracture in rigid cellular PVC foam based on experimental and numerical analyses. Experiments were performed on sharp-cracked specimens using the compact-tension-shear (CTS) test loading device. Foams of three different densities were tested.

Nonlinear Analysis for Mixed Mode Fracture

1985
When fracture occurs in materials such as concrete, rock, mortar and some glassy polymers, stable crack growth often precedes unstable crack propagation. This paper will address the problem of characterizing slow crack growth. In the first section a description of the process zone (the cause of the slow crack growth) will be presented, along with a ...

Mixed Mode Fracture Tests on Concrete

1989
Mixed mode fracture testing should provide a more comprehensive knowledge of concrete in the softening range, which is needed for a complete modelling in finite element codes. After a survey of some mixed mode testing methods which have been applied so far it is shown that all of these are not capable to supply necessary data in a physically clear and ...

Mixed-Mode Fracture Mechanics

2016
Practical structures are not only subjected to tension but also experience shear and torsion loading leading to a mixed-mode interaction. Correspondingly, the stress state ahead of a crack is frequently based on mixed-mode I/II type of interactions, which designate the amplitude of the crack tip stresses because of skew-symmetric loading.

Mixed-mode fracture of a lubricated interface

Acta Metallurgica et Materialia, 1992
Abstract The fracture of an interface containing a liquid was investigated under nominally mixed-mode conditions. The experiments were designed to be a study of a model interface for which frictional effects are minimised. Alternatively, the system could be considered to provide an analogy for an interface along which there is little resistance to ...

A treatment of mixed mode fracture in debonding

Computational Materials Science, 1994
Abstract A strength based fracture criterion is introduced to describe progressive cracking. Separate internal state variables for each principal failure mode ensure consistent treatment of Mode I, Mode II and mixed mode failure. In numerical examples mixed mode debonding is observed at a curved material interface whereas Mode I separation dominates ...

Mixed-Mode Fracture of Solid Propellants

1998
Abstract : This report describes an investigation into the mixed-mode fracture behavior of solid propellants. Experiments were performed at different mixed mode loading conditions at different temperatures and strain rates. The collection of data suggested that while the maximum tangential stress criterion was a reasonable indicator of the onset of ...
