deformational

Deformational is an adjective describing anything related to deformation—the change in size, shape, or volume of a body caused by external or internal forces, temperature, or phase changes. The term is used across disciplines to describe how materials respond to applied stresses and how such responses are manifested as reversible (elastic) or permanent (plastic) changes, or as time-dependent deformation (creep).

In geology, deformational processes encompass brittle deformation, such as faults and joints, and ductile deformation, including

In materials science and engineering, deformational behavior is described by a stress-strain relationship. Elastic deformation is
