Abstract
The temperature and stress fields for short pulse heating of solids are examined. The thermoelasticity is a temperature rate dependent by including temperature rate among the constitutive variables. The strain rate is of the same order of the temperature rate for most of the materials. The peak temperature attains the maximum at the surface and as the locations move at some distance below the surface, the peak temperature reduces. The location of the peak temperature below the surface changes in time due to the finite speed of temperature in the substrate material. The material response to the heating pulse at the surface is slow, because the maximum peak pulse intensity occurs at dimensionless time t = 10, while the peak temperature occurs at around dimensionless time t ≊ 25 at the surface. It is associated with the pulse profile and the energy transfer taking place in the surface region during the heating cycle of the short pulse.
