| Abstract: | In this paper, the axisymmctric buckled states of an annular sandwich plate (Reissner-type sandwich plate) with the clamped inner edge which is subjected to a uniform radial compressive thrust at the clamped outer edge are studied. Firstly, the basic equation of the buckled problem is derived. Secondly, the critical loads for some parameters are obtained by using the shooting method. Finally, We discuss the existence of the buckled states and obtain the asymptotic expansions of the buckled states in the vicinity of the critical loads. |
