MECH_ENG 362: Stress Analysis

Quarter Offered

Spring : Sec 20 MWF 11:00-11:50am, Sec 21 MWF 12:00-12:50pm ; S. Krishnaswamy

Prerequisites

CIV ENG 216

Description

craneTheory of elasticity: elastic stability, principal of minimum potential energy, Raylegh-Ritz methods. Introduction to finite element methods of stress analysis: computer implementation and use of commercial codes. Structural analysis of rods, beams, columns, and plates.

Who Takes It

Students interested in gaining a deeper appreciation of the mechanics of deformable solids than provided in the introductory Mechanics of Materials (Civ Eng 216) course are welcome to take this course. Typically students in mechanical engineering and biomedical engineering (biomechanics specialization) take this course in their junior or senior years.

What It's About

bridgeME 362 provides a fundamental understanding of the mechanics of deformable solids. Starting with the basic concepts of stress and strain, the course walks you through several ways of analyzing structural systems: "exact" methods using the framework of the theory of elasticity; approximate methods using energy principles; and computational methods using finite element techniques.

Lectures

The course meets three days a week for 50-minute lectures. There is also a computer lab (times and dates announced during the first week of class).

Assignments/Evaluation

In the traditional course format (Section 20), there are weekly homework assignments, one midterm, one final exam, and a term project. In the asynchronous course format (Section 21), the course will revolve around team projects (see attached syllabus for details--instructor approval required for registration).
