Thermomechanics of Fiber-Reinforced Composites.
Abstract
The stress analysis of filamentary composites was investigated and a theory was developed for the mechanics of composites reinforced with orthogonal interlocking fibers. A more concise form of nonlocal elasticity was developed and applied to the study of elastic waves and the problem of stress at the tip of a crack. It was found that the stress concentration was finite at the crack tip and goes as the square root of the crack length. By utilizing this result, a fracture criterion was developed based on the maximum stress. In addition, a constitutive theory was developed for nonlocal polar elastic solids and memory dependent nonlocal elastic solids. The outstanding problem of infinite stress at the crack tip was resolved opening new avenues of research for fracture criteria. (Author)
