Cracks, growing at weld toe, tend to form at numerous sites along the transverse width perpendicular to the applied stresses . 焊趾处萌生的裂纹往往在垂直于作用应力方向沿着横向宽度在多处形成。
If an applied stress or pressure drop is not sufficient to break the gel or exceed the yield stress, no flow will occur . 如果施加的应力或压降不足以破坏凝胶或不足以超过屈服应力,则不会有流动产生。
Both of these statements are based on the tacit assumption that the applied stress does not change during the crack growth process . 这些结论都建立在理想的假设上,即实用应用力在裂纹扩展过程中不变。
In certifying that a given crack shape will exemplify leak-before-break behavior, one should consider the effect of crack growth on the applied stresses . 在证实一个给定的袭纹形状将会发生裂前泄露情况时,我们应考虑裂纹扩展对外载的影响。
