Transient Behavior and Stability of Thermoelastic Contact

当两个不同温度的弹性体被压在一起时，所产生的热流会引起接触面积的变形和变化。最近的研究表明，这种情况可能不稳定，但在适当的条件下，可能会产生自我维持的振荡。微扰技术将用于这种振荡现象的分析研究，以探测稳定边界和不稳定开始时的瞬态行为。材料组合将根据其定性稳定性行为进行分类。//

When two elastic bodies of different temperature are pressed together the resultant heat flux causes distortions and changes in the contact area. Recent work has shown that this situation may not be stable but under suitable conditions self-sustaining oscillations may be generated. Perturbation techniques will be used in an analytical study of this oscillation phenomenon to probe the stability boundary and transient behavior at onset of instability. Materials combinations will be classified according to their qualitative stability behavior.//
