MECH 3220 - Properties and Strength of Materials

Credit Hours: 3

This course provides a comprehensive study of stress, strain, and material behavior under various loading conditions. Students will analyze mechanical systems subjected to axial, torsional, bending, and shear forces to determine internal forces, moments, stresses, strains, and deflections. The course covers fundamental stress analysis principles, including equilibrium, normal and shear stress, allowable stress, and limit state design. Strain and deformation concepts are introduced alongside mechanical properties such as modulus of elasticity, Poisson’s ratio, and stress-strain relationships for ductile and brittle materials. Additional topics include statically indeterminate systems, thermal stress, stress concentrations, residual stress, combined loadings, and failure mechanisms such as creep and fatigue, emphasizing safe and effective material selection and component design.

Prerequisite: MECH 2200
