3 ) based on the asymmetrical beam bending theory , the deflections of damaged hull subjected to hogging and sagging moments and shear forces are analyzed accounting for the external loads listed from previous chapter . the effect of shearing deflection on total hull deflection is discussed 3 )在非對稱彎曲梁模型的基礎上,考慮外載荷變化下,計算了宏觀破損后船體彎曲撓度和剪切撓度,并分析了剪切撓度對總撓度的影響。
