Mixed-mode fracture of concrete

International Journal of Fracture, 1988
Mixed-mode fracture of concrete is encountered frequently in design of concrete structures. To accurately analyzed and design a concrete structure, it is essential to understand the failure mechanisms of concrete under mixed-mode types of loading. A model, which was originally proposed for mode I failure of concrete, is extended to characterized mixed ...

Mixed mode fracture of concrete

International Journal of Solids and Structures, 1991
Strain-softening and strain-localization in cementitious and ceramic materials can be described by using a cohesive crack model, with closing forces at the crack tip, which represent plasticity, inclusion interlocking, fibre bridging and any kind of non-linear behaviour.

Mixed mode fracture energy of sprucewood

Journal of Materials Science, 2001
The characterization of Mixed Mode (Mode I and Mode II) behaviour of wood was concentrated on concepts of linear fracture mechanics in the past. Using an adopted version of the splitting test it was possible to obtain complete load displacement curves under different Mixed Mode loading cases for crack propagation along the grain.

The mixed mode brittle fracture criteria in siliding mode fracture

Applied Mathematics and Mechanics, 1985
It is well-known that the present mixed mode brittle fracture criteria are all the opening mode fracture criterion. We consider that mixed mode brittle fracture of sliding mode fracture exists too. Hence we propose three criteria of mixed mode brittle fracture of sliding mode fracture;: the radial shearing stress criterion, the maximum shearing stress ...

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 ...
