collapse mode meaning in English
破坏形式
Examples
- Several types of buckling mode and several types of collapse mode for the stiffened panels are mostly analyzed . it is emphasized on the influence of position of loading plane on the ultimate strength of stiffened panels and numerical calculation of stiffener tripping . at last the interaction of ultimate strength for stiffened panels combined different loads is discussed
文中主要分析了加筋板的几种屈曲模式和几种失效模式，并着重讨论了加载偏心对极限强度的影响和加筋板的侧倾强度数值分析，和简单讨论哈尔滨工程大学博士学位论文了组合载荷作用下的加筋板极限强度的相互关系。 - 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
确定了船体梁整体破坏时的剖面应力分布之后，关键在于确定板架的极限屈曲强度。本文充分考虑了在纵向弯曲、横向压力作用下加筋板可能发生的几种破坏模式，即板架的整体屈曲破坏、梁柱形式的破坏、筋的侧倾、腹板的屈曲并同时考虑了初始焊接残余应力、初挠度的影响，使其更精确的计算加筋板的屈曲强度。对于加筋板中加强筋腹板的局部屈曲，采用解析法推导出筋的腹板的挠度方程及其边界条件，求解相应的方程，从而计算出腹板的局部屈曲应力。
