# The Impact Torsionai Buckling of Elastic Cylindrical Shells with Arbitrary Form Imperfection

• Publish Date: 1993-06-15
• A perturbation analysis for the impact torsional buckling of imperfective elastic cylindrical shells subjected to a step torque is given The imperfection is supposed to be small and has arbitrary form. It is shown that only the imperfection which has the shape of static torsional buckling mode could influence the critical step torque. Finally a formula is presented for the critical step torque.
