Geometry of deformation

Geometry of deformation describes how materials change shape or size under forces. When a material is stretched, compressed, or bent, its internal structure rearranges, altering its geometry—lengths, angles, and shapes. This deformation can be reversible (elastic) or permanent (plastic). Understanding this geometry helps predict how materials will respond to different forces, ensuring safe and effective design in engineering and construction. Essentially, it’s about visualizing how the interior structure and external shape of a material respond and adapt when subjected to external stresses.
