By using the analysis solution of differential equations based on thinshelltheory, the stresses in pressurized long cylinder or piping stiffened with stiffeners were analyzed.
If we let the transverse shear stiffness approach to infinity, the governing equation of refined theory can be reduced to the classical thinshell equation.
