Definition

You can calculate deformations, stresses, and strains in solid materials using structural mechanics, also known as solid mechanics. A structure's strength, like that of a bridge, is frequently assessed in order to avoid damage or accidents. Determining a structure's flexibility and computing dynamic features, such as natural frequencies and reactions to time-dependent stresses, are additional typical objectives of structural mechanics assessments.

Since having proper models for the mechanical behaviour of the material being utilized is one of the fundamentals, the study of solid mechanics has a tight relationship to material sciences. The mathematical descriptions needed for various kinds of solid materials vary greatly. Metals, rubbers, soils, concrete, and biological tissues are a few examples.
