Abstract：With the considerations of delay effect and coupling effect， the thermoelastic dynamic model was established based on the generalized thermoelasticity. The short-time analytical solutions for one-dimension thermal shock problem were deduced according to Laplace transform and inverse transform. Numerical simulation was conducted to discuss the transmission of thermoelastic wave in elastic solid and the influence of delay and coupling effects on the thermoelastic response. The results show that the thermal shock is weakened by delay effect, while this weaken effect can be restrained by coupling effect to some extent during the transient heat conduction.
