shear failure

Shear Failure


(Russian skalyvanie), the destruction of tangentially stressed materials, in which one part of the material is displaced in relation to another part along some plane or surface. In the field of strength of materials this type of failure is given the Russian term srez for most materials. The term skalyvanie is used when the material has a fibrous structure, for instance, wood, and the plane of shear is parallel to the fibers. The term skalyvanie is also sometimes used to indicate the brittle nature of destruction. A distinction is made between shear failure along the fibers and across the fibers. The calculation of shear failure along the grain is of primary importance in the design of joints between wood structural elements.

shear failure, failure by rupture

Failure in which movement caused by shearing stresses in a soil mass is of sufficient magnitude to destroy or seriously endanger a structure.

shear failure

A type of failure of a riveted or bolted joint in which, instead of the material failing, it is the rivet or the bolt that shears off. Ideally, a joint should be designed so that it will fail in shear rather than in bearing, because a shear failure involves only replacement of the rivet or the bolt.

The shear stress-time curve has a larger stress drop after the peak, and the shear stress is not directly down to the end but shows a gradual downward trend because the shear failure of rock also needs to overcome the friction force on the shear surface.
Furthermore, many studies conducted by several researchers [5-13] on shear behavior provide adequate information to ensure that shear failure can be avoided.
Shear failure is mainly caused by the pressure exerted on the backfill by the top plate exceeding the compressive strength of the backfill.
Failure occurs along one shear failure surface when the moisture content is low and, in most cases, the shear failure surface is parallel to the shear angle.

Unlike flexural failure, shear failure can occur suddenly and without warning.
The punching shear failure of the slab-to-column or the footing-to-column connection is undesirable, since it results in a brittle and catastrophic failure of the concrete structures.
Shear failure envelops go upward drift with matric suction increasing, which is shown in Figure 2(a).Simultaneously, Figures 2(a), 2(b), and 2(c) show that the shear strengths are not the same, although the matric suction and normal stress are completely identical.

The results of experiments show that the shear failure of reinforced concrete (RC) slender beams without stirrups is always governed by diagonal tension failure mode rather than compression failure mode.
