What is Shear Strength?

The shear strength of a material is defined as its ability to resist forces that cause the material's internal structure to slide against itself. The shear strength of a material can be measured in either the vertical or horizontal direction. For example, if the force causes the object's layers to slide in the horizontal direction, the material will exhibit horizontal shear strength. Conversely, if the force causes the layers of the material to slide in the vertical direction, the material will exhibit vertical shear strength.
