ES 2410 - Mechanics of Materials

This course introduces the study of mechanics of materials.  Students determine the stresses, strains, and displacements in structures and their components due to the loads or constraints acting on them.  In addition, students investigate structural integrity by examining various failure mechanisms due to material properties or stability limitations.  To help analyze structures, students are introduced to shear and bending moment diagrams, application of singularity functions, work-energy methods, and Mohr’s Circle.
