Abstract : by means of metallographical examination and sem, the microstructure characteristics, macro - and microfractographs of the brittle broken wheel hull bolt of bj212 automobile have been studied. the results show that the thin - headed screw, with excessively deep carbonitriding layer and hardening layer, has less resistance to brittle fracture in the thin area of its head. at the root of the head connecting the stem, a tensile stress may emerge owing to the non - even quenching stress. those are the two reasons for low torque fracture of bolt
文摘:藉助金相、掃描電鏡等手段對低扭矩脆斷的bj212汽車輪殼螺栓的金相組織特徵，宏觀和微觀斷口形貌等進行了研究，結果表明：這種頭部薄的螺栓，滲層和淬透層過深，使頭部薄區脆斷抗力降低，在頭部與桿的根部，由於淬火應力不均勻導致根部產生拉應力，均是導致螺栓低扭矩斷裂的原因。 -

Rms titanic, on her maiden voyage from southampton, england, to new york city, had sideswiped an iceberg 2. 5 hours earlier, popping rivets and buckling the hull ' s iron plates deep below the waterline
英國郵船泰坦尼克號正在進行從英格蘭的南安普敦到紐約市的處女航，在沉沒前的兩個半小時，它從側面撞上了一座冰山，鉚釘砰砰地斷裂，吃水線下面的船身鐵板彎曲變形。 -
The concept of the longitudinal strength of ship hulls has changed and advanced greatly as the study on the failure mechanism of the hull is getting deep. by taking account the failure modes of yielding, buckling and their combination, as well as the non - linear interactions between structural members, the ultimate longitudinal bending moment is defined by the moment corresponding to the point with zero slope on the moment - curvature curve of the ship hull
但隨著對船舶破壞機理的認識和研究發現，在研究船體的總縱極限強度時，必須考慮構件的屈曲、屈服等各種可能的破壞模式，要考慮受壓構件屈曲后及崩潰后的非線性性能的影響，要考慮組成船體的各個構件發生破壞的漸進性質和相互作用等。
