• Resumen

  • The present research paper handles a 2D deformation in a homogeneous thermoelastic photothermal semiconducting medium subjected to a magnetic field and initial stress with an internal heat source. The problem is framed in the dimensionless form and resolved utilizing the normal mode analysis method. Based on a numerical study using the parameters of silicon as a target, the physical data were attained and tested. They presented the magnetic field and initial stress. It is observed that the magnetic field and initial stress exert some influence in the P-waves in a photothermal semiconducting medium due to internal heat source. The distribution of these quantities was represented graphically with and without the internal heat source, as well as the magnetic field and the initial stress.
