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(yīng)力方向沿著橫向?qū)挾仍诙嗵幮纬伞?i class="labawb" onClick="playMp3('sound_c_1')">
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(yīng)力或壓降不足以破壞凝膠或不足以超過屈服應(yīng)力,則不會(huì)有流動(dòng)產(chǎn)生。
