Shear failures in frames and slabs

Building Research and Practice, 1974
A most serious type of failure in concrete construction is a defect in shear resistance. Collapse can come unheralded by prior deflection and cracking. Dr Feld, New York consulting engineer and author of ‘Lessons from Failures of Concrete Structures’, here considers aspects raised by specific instances of failure.

Dynamic Shear Failure of Materials

2009
Dynamic shear failure is addressed from the experimental point of view, presenting first the shear compression specimen (SCS) that is used to characterize the mechanical properties of various materials subjected to dynamic shear loading. Results are reported for various metallic alloys, addressing the stress–strain curve itself and the related issue of

Shear Failure of Anistropic Rocks

Geological Magazine, 1960
AbstractThe two-dimensional theory of two simple generalizations of the Coulomb-Navier criterion for shear failure is developed. The first of these refers to a material with a single plane of weakness which has a different shear strength and coefficient of internal friction from the remainder of the material.

Failure During Sheared Edge Stretching

Journal of Materials Engineering and Performance, 2008
Failure during sheared edge stretching of sheet steels is a serious concern, especially in advanced high-strength steel (AHSS) grades. The shearing process produces a shear face and a zone of deformation behind the shear face, which is the shear-affected zone (SAZ). A failure during sheared edge stretching depends on prior deformation in the sheet, the

Instability, shear banding, and failure in granular materials

International Journal of Solids and Structures, 2002
Two modes of decrease in load bearing capacity of granular materials are discussed in view of experimental results. Both relate to the fact that frictional materials exhibit nonassociated plastic flow and they undergo considerable volume changes, either contraction or dilation.

Modes of dynamic shear failure in solids

International Journal of Fracture, 2000
The technique of loading edge cracks by edge impact (LECEI) for generating high rates of crack tip shear (mode-II) loading is presented. The LECEI-technique in combination with a gas gun for accelerating the impactor is used to study the high rate shear failure behaviour of three types of materials.

Hydrogen-induced shear type failure

Scripta Metallurgica, 1988
Etude experimentale du mode de rupture dans des eprouvettes lisses en acier non allie chargees cathodiquement en hydrogene, soumises a des essais de traction. Analyse du role de la fissuration superficielle induite par hydrogene sur le phenomene de fragilisation par hydrogene en controlant la propagation finale.

Failure state of a sand in simple shear

Canadian Geotechnical Journal, 1988
The stress state in many practical geotechnical problems is analogous to simple shear strain. However, the devices available to test soil samples in simple shear strain impose nonuniform stress and strain fields. Consequently, the interpretation of results from simple shear tests is often questioned.
