Final answer:
The stress and strain caused by the imposition of loads on building materials is referred to as material deformation.
Step-by-step explanation:
The stress and strain caused by the imposition of loads on building materials is referred to as material deformation.
When external forces are applied to an object, it may undergo a change in its shape or size, resulting in deformation. This deformation can be in the form of stretching, compressing, twisting, or shearing of the material. The stress caused by the applied forces leads to the deformation, and the extent of deformation is described as strain.
