6.2 Types of Deformations

Three types of deformations can be distinguished as follows:

Longitudinal or Tensile Deformation

This is the deformation in length for an object in the form of a wire or a cylinder of negligible cross- sectional area compared to the length when the applied forces are parallel to the length.

Shear Deformation

This is the deformation in area and shape when applied forces are parallel to a surface.

Bulk Deformation

This is the deformation in volume and/or shape when applied forces are normal to each and every point of the surface of the object.
