The governing equations of non-linear dynamic response of an axisymmetric elastic thin circular plate subjected to an arbitrarily transverse force and a thermal energy deposit are formulated.Deformation features of thin circular plates and the factors that affect failure are discussed by a quasi-static analysis.It is shown that thermal buckling is one of the major failure modes of thin circular plates in the case of short duration thermal energy deposit. Thermal buckling always occurs before reverse bulging or reverse plugging.Similar to the increase of the transverse load,the increase of the power level of thermal energy deposit will accelerate the thermal buckling.The temperature dependence of material properties and the time-space distribution of thermal energy deposit both significantl
