Principles of stress and strain in 3D, indeterminate structures, failure theory, and energy methods in solid mechanics. MET 320 Strength of Materials II (3) This course consists of three main subject areas; a study of statically indeterminate structures, a study of stresses and strains in three dimensions, and a study of energy methods in solid mechanics. Statically indeterminate structures are studied for stresses and deformations. The types of indeterminate structures studied are axially loaded members, including temperature changes; torsionally loaded members, including geared connections; and bending members. Stresses and strains are studied in three dimensions with Mohr's Circle to identify principal stresses and absolute maximum shear stress, to understand Hooke's Law and other material property relationships, and to apply various failure or yield theories. Energy methods are studied so that stresses and deformations from impact loading of structures can be analyzed and included in the design of axial, torsion, and bending structures. Energy methods are also used to determine the static deformation of complicated structures. Other miscellaneous topics may include unsymmetric bending, bending of multi-material beams including reinforced concrete, bending of curved beams, shear center, combined loadings, torsion of non-circular members, columns, and true stress and true strain.
