bucking strength meaning in English
浸渍强度；弯曲强度
Examples
- This thesis used along caldwell ' s direct calculation method of the ultimate strength of ship hull girders , considered the double bottom and upperwing tank to ship ultimate strength contribution , first defined the stress distribution of the whole section of the ship girders . that is : in the sagging condition , deck and side shell of nearby deck remain the ultimate bucking strength , double bottom remain the yield stress . and the other parts keep elasticity
本文沿用caldwell等人直接计算船体极限强度的思想，考虑双层底和顶边水舱对船体极限强度的贡献，首先将船体梁整体破坏时剖面应力分布确定为：在中垂状态下，甲板及甲板附近的舷侧均屈曲，双层底区域则均屈服，其他部分保持弹性状态；在中拱状态下，双层底及之间的底舷侧均屈曲，甲板及顶边水舱区域均屈服，其他部分则保持弹性状态。 - 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。
