Shear strength
From Wikipedia, the free encyclopedia
Shear strength in engineering is a term used to describe the strength of a material or component against the type of yield or structural failure where the material or component fails in shear.
In structural and mechanical engineering the shear strength of a component is important for designing the dimensions and materials to be used for the manufacture/construction of the component. For example, beams, plates, bolts etc. In a reinforced concrete beam, the main purpose of stirrups is to increase the shear strength.
σ1 = Major Principal Stress;
σ3 = Minor Principal Stress;
& Shear strength τ = (σ1 - σ3)/2
