ME C124 - Mechanical Behavior of Engineering Materials [3 units]
CATALOG DESCRIPTION
This course covers elastic and plastic deformation under static and dynamic loads. Prediction and prevention of failure by yielding, fracture, fatigue, wear, and environmental factors are addressed. Design issues pertaining to materials selection for load-bearing applications are discussed. Case studies of engineering failures are presented. Topics include engineering materials, structure-property relationships, materials selection for design, mechanical behavior of polymers and design of plastic components, complex states of stress and strain, elastic deformation and multiaxial loading, plastic deformation and yield criteria, dislocation plasticity and strengthening mechanisms, creep, effects of stress concentrations, fracture, fatigue, and contact stresses. Also listed as Materials Science and Engineering C113.

COURSE OBJECTIVES
The central theme of this course is on the mechanical behavior
of engineering materials for load bearing applications.
The main objectives are to provide students with basic
understanding of deformation and multiaxial loading,
plastic deformation and yield criteria, dislocation plasticity
and strengthening mechanisms, creep, effects of stress concentrations,
fracture, fatigue, and contact stresses.
In addition, the course examines constitutive laws
pertaining to linear and nonlinear elastic behavior,
failure by yielding, wear, fatigue, and fracture mechanisms at
different scales, and mechanical properties of engineering
materials including metals, ceramics, polymers, and composites.
DESIRED COURSE OUTCOMES
Understand various types of deformation and failure of materials
due to various static and dynamic loadings.
Relate microscopic to macroscopic material behaviors.
Learn how to engineer the material properties to meet certain specifications.
Determine the safety factor for various possible failure modes and loadings.
