Course Overview

The mechanical properties of a material affect how it behaves as it is loaded. The elastic modulus of the material affects how much it deflects under a load, and the strength of the material determines the stresses that it can withstand before it fails. The ductility of a material also plays a significant role in determining when a material will break as it is loaded beyond its elastic limit. Because every mechanical system is subjected to loads during operation, it is important to understand how the materials that make up those mechanical systems behave.

This course discusses the mechanical properties of materials that are relevant to the design and analysis of mechanical systems, including:

  • Calculation of stress and strain
  • Stress-strain curve
  • Hooke's law
  • Poisson's ratio
  • Strain hardening
  • Elastic and plastic strain
  • Ductility
  • Ductile and brittle materials
  • Strain energy, including a discussion of the modulus of resilience and modulus of toughness
  • Stress-strain curve approximation using the Ramberg-Osgood equation
