摘要
抛弃任何有关位移和应力模式的假设,引入δ-函数,对正变异性连续开口圆柱壳建立状态方程.给出薄的、中厚的和强厚的叠层连续开口圆柱壳静力问题的统一的精确解.数值结果和SAPS解进行了对比.
Discarding any assumptions about displacement models and stress distribution and introducing δ-function into the present study, the state equation for the continuous orthropic open cylindrical shells is established. An identical exact solution is presented for the statics of thin, moderately thick and thick laminated continuous open cylindrical shells. Numerical results are obtained and compared with those calculated using SAP5.
