Cracks, growing at weld toe, tend to form at numerous sites along the transverse width perpendicular to the applied stresses . 焊趾處萌生的裂紋往往在垂直于作用應力方向沿著橫向寬度在多處形成。
If an applied stress or pressure drop is not sufficient to break the gel or exceed the yield stress, no flow will occur . 如果施加的應力或壓降不足以破壞凝膠或不足以超過屈服應力,則不會有流動產生。
Both of these statements are based on the tacit assumption that the applied stress does not change during the crack growth process . 這些結論都建立在理想的假設上,即實用應用力在裂紋擴展過程中不變。
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 . 在證實一個給定的襲紋形狀將會發(fā)生裂前泄露情況時,我們應考慮裂紋擴展對外載的影響。
