摘要
Abstract
For solving the inconsistence problem among existing theoretical solutions of the critical tem-perature for FGM cylindrical thin-shell,the theoretical solution of critical temperature was deduced for a FGM cylindrical thin-shell subj ected to a uniform temperature rise based on Donnell equation.And then the numerical solutions of the FGM cylindrical shell were constructed separately.Lastly,by comparing analysis between the theoretical solution and numerical solution of cylindrical thin-shell under different l/R,δ/R and R,the exact solution was obtained by introducing a modified coefficient.The results bene-fit to scientifically design related FGM thin-shell structures.关键词
