ultimate bending strength 中文意思是什麼
ultimate bending strength
解釋
極限抗彎強度-
In the hogging condition, double bottom and the side shell remain the ultimate bucking strength, deck and upperwing tank remain the yield stress, and the other parts keep elasticity. then the key to calculate the ultimate strength of ship hull girders is to ascertain the ultimate bucking strength of the stiffened panels. in this regard, the developed formulation is designed to be more sophisticated than previous simplified theoretical method for calculating the ultimate strength of stiffened panels under combined in - plane bending and lateral pressure. fabricatio n - related initial imperfections ( initial deflections and residual stresses ) are included in the panel ultimate strength calculation as parameters of influence. all possible collapse modes involed in collapse of stiffened panels, including overall buckling collapse, column or beam - column type collapse, tripping of stiffeners and local bukling of stiffened web are considered
確定了船體梁整體破壞時的剖面應力分佈之後，關鍵在於確定板架的極限屈曲強度。本文充分考慮了在縱向彎曲、橫向壓力作用下加筋板可能發生的幾種破壞模式，即板架的整體屈曲破壞、樑柱形式的破壞、筋的側傾、腹板的屈曲並同時考慮了初始焊接殘余應力、初撓度的影響，使其更精確的計算加筋板的屈曲強度。對于加筋板中加強筋腹板的局部屈曲，採用解析法推導出筋的腹板的撓度方程及其邊界條件，求解相應的方程，從而計算出腹板的局部屈曲應力。 -
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。
