摘要
以位移和热流为基本未知函数,利用势算子理论推导了均质材料耦合热弹性动力学的两个热流势能型最小值原理。
Taking the displacement and heat flux as elementary unknown founctions and using poten-tial operator theory,the present paper deduces two minimum principles of heat flux potential energytype on coupled thermo-elastodynamics ln uniform materials.
