采用恒定加载和重复加载两种方法研究了天然胶硫化胶的剪切生长。结果已经用先前提出的撕裂能的概念来表示。随着反复加载下的切割生长，尖端从最初的光滑变得粗糙，同时生长速度显著下降到最终的稳定值。已经讨论了这种粗化的一些后果。还使用两种不同类型的试件对重复加载下的切割生长进行了测量。以前提出的断裂准则预测了两个试件的行为之间存在一定的关系，这一点已经得到了实验的证实。
Cut growth in natural rubber gum vulcanizates has been studied using both steady and repeated loading. The results have been expressed in terms of the concept of the energy for tearing that has been put forward previously. With cut growth under repeated loading the tip, initially smooth, becomes rough and the rate of growth simultaneously decreases markedly to a final steady value. Some consequences of this roughening have been discussed. Measurements of cut growth under repeated loading have also been made using two different types of test piece. A rupture criterion, which has been previously proposed, predicts a definite relationship between the behavior of the two test pieces, and this has been confirmed experimentally.
