MS 243A Course Overview

Fracture of Engineering Materials

Description of the Course
Lecture, four hours; laboratory, two hours; outside study, four hours. Requisite: course 143A. Engineering and scientific aspects of crack nucleation, slow crack growth, and unstable fracture. Fracture mechanics, dislocation models, fatigue, fracture in reactive environments, alloy development, fracture-safe design. Letter grading.

Background students will need
Although prerequisites are not enforced for graduate students, it is strongly recommended that each student has taken courses equivalent to Mechanical Behavior of Materials (MSE 143A) or Strength of Materials (MAE 156A).
