Course Number: FLR-001
Course Field: Structural Failure
PDH Credits: 5

Course Overview

Fracture mechanics is a methodology that is used to predict and diagnose failure of a part with an existing crack or flaw. The presence of a crack in a part magnifies the stress in the vicinity of the crack and may result in failure prior to that predicted using traditional strength-of-materials methods.

This course discusses:

  • Stress concentrations around cracks
  • Modes of loading
  • Stress intensity factor
  • Fracture toughness
  • Initial crack size
  • Plastic zone size for plane-stress and plane-strain
  • Ductile vs. brittle fracture
  • Static fracture analysis methods, including:
    • Linear Elastic Fracture Mechanics (LEFM)
    • Failure Assessment Diagram (FAD)
    • Residual Strength Curve
  • Brief introduction to fatigue crack growth
