thermoelastic effect 弹性材料在伸长时会发热，回缩时会吸热，而且伸长时的热将就随伸长率而增加，这种现象称为热弹效应。 如橡胶伸长变形时，分子链段或分子链由无序排列变有较有序的排列，引起熵值减少；同时由于分子间的内摩擦而产生热量；分子规则排列而发生结晶过程而放出热量。由于上述三种原因，拉伸橡胶时分发热。
边界条件对耦合效应有较大的影响，较强的边界条件使椭圆板热弹耦合自由振动的频率变低，但振荡幅度增大。
The boundary conditions has strong influence on the coupling effect, the stronger it is, the smaller frequency of free vibration is but the larger amplitude is.
