Mechanics of Material
Mechanic of materials is a discipline of mechanical engineering that studies the deformable solids using numerical models. The resistance of an element is defined as its ability to resist efforts and forces applied without breaking, permanent deformation or acquire deterioration.
For mechanical design elements with complex geometries the strength of materials is often insufficient and need to use techniques based on the theory of elasticity or the mechanics of deformable solids. These problems in terms of stresses and strains can then be solved by using numerical methods such as finite element analysis.
