- 1. Solid mechanics is the branch of mechanics that deals with the behavior of solid materials when subjected to various types of loading. It encompasses the study of stress, strain, deformation, and elasticity of solids, including structures such as beams, columns, and shells. Understanding solid mechanics is crucial for designing and analyzing structures to ensure they can support different types of loads and operate safely under various conditions. Applications of solid mechanics can be found in engineering fields such as civil engineering, mechanical engineering, aerospace engineering, and materials science.
