Non Linear Buckling Analysis of Sandwiched Cylindrical Shells
This present work is devoted to Non linear buckling analysis of seven layered sandwiched cylindrical shells. The
shell is sandwiched structure consists of main core and two three layer faces. Numerical FEM model for the shell has been
made. The calculations have been performed with the use of ANYS APDL code for elastic shell of various dimensions. The
linear and non linear analysis of the shells have been performed with the use of FEM. Critical buckling pressure is calculated
for a family of seven layered shells subjected to external pressure. The results of these investigations are presented on the
graphs. And by adding the stringer along the cylinder shell the critical buckling pressure of shell is calculated and the result
unstiffened and stringer stiffened shell is compared.
