Abstract

Gives a brief synopsis of the history of industrial injury compensation before going on to consider the Occupational Safety and Health Act. Outlines the objectives of workers’ compensation and the categories under which claims can be made. Considers the cost of workers’ compensation and profiles ways in which leading companies attempt to reduce these through promoting workplace safety. Provides an action plan to prevent work related disabilities occuring and highlights other opportunities for cost control.

Abstract

Purpose

The purpose of this paper is to study the deformation of a rotating generalized thermoelastic medium with two temperatures under hydrostatic initial stress subjected to different types of sources.

Design/methodology/approach

The methodology applied here is the use of integral transforms to obtain the components of displacement, force stress, conductive temperature and temperature distribution in Laplace and Fourier domain. The general solution obtained is applied to a specific problem of a half‐space subjected to concentrated force, uniformly distributed force and a moving source. These components are then obtained in the physical domain by applying a numerical inversion method. Some particular cases are also discussed in the context of the problem. The results obtained are also presented graphically to show the effect of rotation and gravity.

Findings

The variations of all the quantities and for all the mediums are similar for concentrated force and distributed forces applied along the free surface of the solid. The values of these quantities are very close to each other for GTES and GTESWG. Deformation of a body depends on the nature of force applied as well as the type of boundary conditions. The variations of all the quantities are more uniform in nature when a force of constant magnitude moves along the surface of solid with some velocity.

Originality/value

Such types of problems in rotating media will find great applications in many dynamical systems and industries.
