Mechanics of Composite Materials.
Abstract
The primary objective was to construct viable micromechanical continuum models to predict the following response measures of composite materials subject to thermomechanical process: (1) global and local stress, deformation, and diffusive (thermal and/or moisture) fields; (2) failure modes and damage accumulation; and (3) residual properties of damaged composites. Additional objectives included the development of associated variational principles from which the continuum models might be transformed to finite element form, and the performance of case studies in an effort to validate the modeling process. The model construction methodology employed is based upon the mixture theory with microstructure concept. Accordingly, all global properties are determined from the composite geometry, and the properties of the microcomponents and the microcomponents interfaces. Such as theoretical framework allows a considerable improvement in modeling capability, and provides a simulation tool that allows one to rationally guide material development and selection. In addition, and in contrast to direct micromodeling by finite difference or finite element methods, it furnishes a very efficient and inexpensive computation tool.
