Study on Two-dimensional Generalized Thermoelastic Problem under Pulsed Laser Heating

XIA Rong-hou TIAN Xiao-geng SHEN Ya-peng (MOE Key Laboratory of Strength and Vibration,Xi'an Jiaotong University,Xi'an 710049,China)  
A generalized thermoelasticity problem for semi-infinite plane locally induced by pulsed laser heating was studied by adopting L-S generalized thermoelasticity.In order to avoid the loss of precision in general integral transformation method,the finite element control equations were solved directly in the time domain.The temperature distributions as well as displacement and stress distributions were obtained and represented graphically under pulsed laser heating in semi-infinite plane.The results show that the present method is an effective and exact numerical analysis method for the generalized thermoelasticity problem,and the maximum temperature on the structure always located near the thermal wave front and reduced gradually alone with time process,the stress near the thermal wave front is also higher than other region.
