Experimental Study and Numerical Calculation of Stability andLoad-Carrying Capacity of Cylindrical Shell with Initial Dent
含有初始凹陷圆柱壳稳定承载能力的实验研究与数值计算

Study of the stability and load-carrying capacity of a cylindrical shell with initial axisymmetric dent under uniform axial compression was carried out.Through experimental investigation,the critical loads for different dent lengths and different cylindrical shell lengths were obtained.At the same time,the dent was just regarded as an irregular change of whole structure regardless of the process of dent formation,a 3-dimensional finite element model was established to analyze the stability of cylindrical sh...
