摘要
应用变积方法建立了准静态电磁热弹性体的势能原理和第二类H-R型广义变分原理,并检验了变分原理的正确性,为电磁热弹多场问题的近似计算提供理论基础。
Potential energy principle and the second H-R generalized variational principles of quasi-static electro-magneto-thermo-elasticity are established by variational integral method in this paper. The validity of variational principles was verified. It offers theoretical support for approximate calculation of multi-physics field problem of electro-magneto-thermo-elasticity.
