Abstract
Purpose The purpose of this paper is to investigate the response of viscoelastic beam resting on a Winkler's foundation and subjected to an axial initial stress, thermal load and an ultra-fast laser heating. Design/methodology/approach In this introduced model, the authors considered the interaction design between the vertical springs only. The beam is considered as an Euler-Bernoulli beam exposed to sinusoidal varying heat. Findings The deflection and the temperature response of the beam are obtained using Laplace transform and its numerical inversion method. In the numerical example, the effect of the laser pulse duration and viscous damping coefficient on the transverse displacement response of the beam is discussed. The thermoelastic interactions of the beam due to the axial load are also illustrated. Originality/value Physical views of this paper may be useful for the design and vibration analysis of micro-resonators and micro-sensors applications. In addition, the utilization of laser-ultrasonic technology has found wide applications in lab environments, and in an expanding number of cases, it is extending to the industrial field and realm application.
