Abstract

This paper studies the thermoelastic dynamic response of a simply supported beam under movable temporally non-Gaussian laser pulse. The heat conduction equation of the problem was solved by using the method of separation of variables. The Green’s function for the forth-order partial differential equation was derived and was used to solve the vibration equation of a heated beam. The temperature, deflection, and strain of the beam were derived analytically and their variations with time and space were illustrated. The influences of moving speed and duration time of the laser pulse on the dynamic responses were also analyzed. It was interesting to observe the propagation of strain wave along the beam axis during the irradiation period of the laser pulse.
