A SEMI-ANALYTlCAL SOLUTION FOR THERMAL STRESS ANALYSIS OF LAMINATED COMPOSITE CYLINDRICAL SHELLS
-
摘要: 通过对Ｈｅｌｌｉｎｇｅｒ－Ｒｅｉｓｓｎｅｒ变分原理的修正，导出了变温作用下层合圆柱厚壳的状态方程及其半解析法，该方法在ｚ－θ曲面内采用通常的有限元离散，而沿壳厚（ｒ）方向采用状态空间法给出解析解答，且通过采用状态转移矩阵，建立了层合圆柱壳内外表面应力和位移之间的关系式，然后利用打靶法进行求解，从而大大降低了计算中的未知量数目。Abstract: The state equation for thermal stress analysis of laminated composite cylindricalshells is derived and a semi-analytical solution is presented by the combination betweenfinite element method and state space control method.By the employing the transfermatrix method,the continuity of interlaminar stresses and displacements is satisfied,andthe variable numbers are reduced greatly.
