**Shear stress**, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed

**stress**. The resultant

**shear**is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes.

Then, what is the difference between shear stress and shear strength?

**Shear stress**is simply the

**resistance**developed

**in the**body under the application of

**shear force**, let say transverse

**force in a**beam.

**Shear strength**is the maximum

**shear stress**a component or part can bear under the application of

**shear force**before failure.

What is the shear strength of mild steel?

The factor of 0.6 used to change from tensile to shear force could vary from 0.58–0.62 and will depend on application. Steel called EN8 bright has a tensile strength of

**800 MPa**and mild steel has a tensile strength of**400 MPa**.What is a shear strength test?

**Shear Strength Testing**.

**Shear testing**is performed to determine the

**shear strength**of a material. It measures the maximum

**shear stress**that may be sustained before a material will rupture.

**Shear testing**is commonly used with adhesives and can be used in either a tensile or comprehensive method.
