[′shir ‚plān]
(geology)
(hydrology)
A planar surface in a glacier, usually laden with rock debris, attributed to discontinuous shearing or overthrusting.
(mechanics)
A confined zone along which fracture occurs in metal cutting.

This is important as cracks tend to grow specific planes, usually on or near the maximum tensile plane or the maximum shear plane [8, 11].
One shear plane cross-cutting the foliation caused the failure of the specimen with sub-horizontal foliation.
Since there was no shear plane in the intact samples therefore shear planes were produced in the samples using geological hammer.
Visual examination of some of the samples after the test indicated that these samples showed no distinct shear plane unlike brittle materials.
Cracks start on the localized shear plane at or near high stress concentrations, such as persistent slip bands, inclusions, porosity, or discontinuities.
The mechanical parameters tested by different apparatuses all have differences attributing to the differences of characteristics of shear plane and stress conditions.
The tension developed in roots is resolved with a tangential component resisting shear and a normal component increasing the confining pressure on the shear plane.
5a) is highest at the shear plane and decreases along the chip--tool interface and least below the uncut surface and the free end of chip.
Under these conditions shear plane angle becomes very small leading to greater plastic energy dissipations in the workpiece subsurface.
The J-C and Z-A stress contours for a cutting speed of 82 m/min shows better stress distribution in the shear plane than the contours for a cutting speed of 34 m/min.
The zeta potential is an electrical potential at the shear plane of the electric double layer on colloid particles.
