Özet
Modelling of laser pulse heating of metallic substrates reduces the experimental cost and optimizes the laser heating parameters. In the present study, exponentially time-varying laser pulse heating with convective boundary conditions at the surface is considered. The closed-form solution for temperature distribution at the surface is presented. The effects of the heat transfer coefficient (h*) and pulse parameter (β*) on the time corresponding to the maximum surface temperature (tTmax*) are investigated. It is found that the influence of the heat transfer coefficient on tTmax* is significant for h*≥0.02. Moreover, reducing the pulse parameter lowers tTmax*.
