Abstract: 

The effect of strain hardening modulus on axisymmetric buckling of circular cylindrical shells made of aluminum and steel materials is investigated, so the nonlinear dynamic equations of cylindrical shells with different strain hardening modulus for cylindrical shells made of aluminum material and different linear and multi-linear strain hardening modulus for cylindrical shells made of steel material are solved for three types of boundary conditions and two types of loading. It is found that under investigated conditions, changing of strain hardening modulus for cylindrical shells made of aluminum and steel materials transmit the buckling shape from plastic buckling to progressive buckling.
