Summary
Deformation in solids occurs when external forces change their shape, length, or volume. It involves stress (internal resistance) and strain (measure of deformation). Key concepts include Young's modulus, types of stress (tensile, shear, volumetric), and the stress-strain curve, which illustrates material behavior under stress, distinguishing ductile from brittle materials.
