Effect of Heterogeneity, Irregularity, and Reinforcement on the Stress Produced by a Moving Load on a Self-Reinforced Composite Half-Space

Abstract
The present study deals with the stress produced in an irregular heterogeneous self-reinforced composite half-space due to a load acting as a shearing force and moving along the free surface. The expression of shear stress produced in this case was obtained in closed form. The effect of heterogeneity, reinforcement, maximum depth of irregularity, and the irregularity factor on shear stress is the highlight of the study. In addition, the effect of different shapes of irregularity on shear stress is discussed through the irregularity factor. Moreover, a comparison is made for three different cases of irregularity, namely, rectangular, parabolic, and no irregularity. As a special case of the problem, the stress produced because of a moving load acting as a shearing force in an isotropic half-space with and without heterogeneity and irregularity is discussed. A comparative study of a self-reinforced composite medium and an isotropic medium in the present context of the problem was performed using graphs, and important peculiarities were traced out.
