A novel model of microelongation thermomechanical photoacoustic waves in excited semiconductor materials

Abstract

In this study, we discussed the photothermal effect on a microelongated thermoelastic plate under the influence of acoustic pressure. This study is very important in many fields and has a wide application in industries. The problem is studied in the two-dimensional plane to obtain the thermoacoustic and mechanical waves behavior. Normal mode analysis is used to get the exact solution of the problem. Many comparisons between the physical quantities are made according to the different values of physical constants of many semiconductor materials. Graphical illustrations depict the numerical outcomes for the examined fields both with and without microelongation parameters.
