Abstract

This paper deals with the application of meshless generalized finite difference (GFD) method for laser pulses-induced thermoelastic wave propagation in porous materials. The governing and constitutive equations are derived for a porous rod using Moore-Gibson-Thompson (MGT) theory of coupled thermoelasticity and Love-Bishop elasticity theory for the first time. The porous rod is subjected to laser shock pulses at one of its ends. The dynamic volume fraction balance equation and the effect of porosities are taken into account to derive the MGT-based heat conduction model in porous materials. The GFD is employed to solve the governing equations in Laplace domain and then the obtained fields’ variables are transferred to time domain using Talbot Laplace inversion technique. The transient behaviors of all fields’ variables such as displacement, temperature and voids’ volume fraction are obtained for various values of the time relaxation parameter in the MGT theory. Also, propagations of thermoelastic wave fronts in displacement, temperature and volume fraction are illustrated at various time steps. To verify the proposed solution approach, the derived governing equations and results, a comparison with a good agreement is conducted in the paper.

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
