Micromechanics as a Basis for Damage Mechanics

  • Conference paper
Local Mechanics Concepts for Composite Material Systems

Part of the book series: IUTAM Symposia ((IUTAM))

  • 194 Accesses

Abstract

A review of the micromechanics of composites is given herein. This includes the concepts of geometric scales, the representative volume element, and volume averaging of state variables in the representative volume element. These concepts are first reviewed for composites composed of linear elastic constituents and then extended to include the case of composites with time dependent microcracks. A brief review is then given of recent micromechanics solutions which include the effects of damage. Results are discussed for both laminated composites and composites with one or more inelastic phases.

The development of locally averaged damage dependent constitutive equations is discussed, and evolution laws for damage accumulation are reviewed. Finally, a brief overview of the role of micromechanics in life prediction is presented.
