1. relating to or causing a change in shape or form; involving deformation
Usage: technical; often used in engineering, geology, and materials science

Examples

• The deformational forces acting on the rock layers caused them to fold and buckle.
• Engineers studied the deformational behavior of the metal under extreme heat.
• Tectonic deformational processes shaped the mountain range over millions of years.
• The material's deformational properties were tested in the laboratory.
• Stress-induced deformational changes were observed in the structural analysis.
