翻译后摘要：被认为是一个裂纹的长度2a传播小，恒定的速度通过一个粘弹性带的宽度2b。在平面应力状态下，计算了裂纹扩展线上的应力和裂纹面的形状。讨论了聚氨酯橡胶（Solithane 113 - 50/50）的相关材料性能。材料表征的结果用于计算作为施加的应变和温度的函数的裂纹速度。理论和实验之间存在很好的一致性。
Abstract : A crack of length 2a which propagates with small, constant speed through a viscoelastic strip of width 2b is considered. The stress on the line of crack advancement and the shape of the crack surface are calculated for a state of plane stress. The relevant material properties are discussed and presented for a Polyurethane rubber (Solithane 113 - 50/50). The results of the material characterization are used to calculate the crack speed as a function of applied strain and temperature. Good agreement is found to exist between theory and experiment.
