论文摘要
使用有限元方法，我们定量分析了经历负载过程的粘弹性固体中的温度场演化。特别是我们研究了开尔文内的温度场 - voigt型粘弹性体，切成薄。我们发现，粘度显着有助于温度场的变化，并且由负载引发的温度场变化 - 解载过程被强烈集中在薄切口的尖端上。定性的预测温度场对应于在实验中观察到的温度场，该实验集中在材料内部的裂纹尖端（例如填充橡胶）内的裂纹尖端上同时进行热量测量。
Using the finite element method we quantitatively analyse temperature field evolution in a viscoelastic solid undergoing a loading--unloading process. In particular we investigate the temperature field inside a Kelvin--Voigt type viscoelastic body with a thin cutout. We find that the viscosity significantly contributes to the temperature field changes, and that the temperature field changes initiated by the loading--unloading process are strongly concentrated at the tip of the thin cutout. The predicted temperature field qualitatively corresponds to the temperature field observed in experiments focused on simultaneous heat and strain measurements at the crack tip inside materials such as the filled rubber.
