Local　temperature　of　cylindrical　shells　at　the　position　of　facula　rises　rapidly　under　intensive　laser　irradiation.　It　changes　the　material　property,　causes　thermal　stresses　and　reduces　the　capacity　of　loading.　The　finite　element　model　is　established　for　the　cylindrical　shell　and　changing　of　the　material　parameters　with　temperature　was　considered.　The　temperature　field　and　stress　field　of　the　structure　exposed　to　laser　irradiation　with　uniform　light　intensity　and　Gauss　light　intensity　are　simulated.　The　different　effects　on　the　temperature　field　and　the　stress　field　under　two　kind　of　light　intensity　are　compared.　The　effect　of　light　intensity,　facula　dimension　and　irradiating　time　to　the　temperature　field　and　stress　field　are　analyzed.　Effects　of　changing　specific　heat　and　Young＇s　modulus　on　the　temperature　field　and　stress　field　are　discussed.
