Course Goals: On completion of EN175, students shall

1. Understand the mathematical and physical foundations of the continuum mechanics of solids, including deformation and stress measures; constitutive relations; failure criteria; have the ability to pose and solve boundary value problems involving deformable solids; and understand the basis for numerical methods in solid mechanics.

2. Be proficient in the use of a modern finite element analysis program (ABAQUS/CAE) for analyzing stress, deformation and failure in components, assemblies and structures.

3.  Possess the ability to apply the principles of solid mechanics to solve engineering problems and to design systems or components to meet desired needs; including (a) to idealize a system or component for the purposes of stress analysis; (b) to use appropriate numerical and analytical techniques to model the system (c) to interpret and draw appropriate conclusions from the results and (d) present results and conclusions clearly in the written and oral presentations.
