| Abstract: | The failure of coupled crack extension and local buckling in cylindrical shells with circumferential through-crack subjected to combined axial compression and bending loads is experimentally investigated. The variation of load carrying capacity of the shell with the crack extension during failure is observed and recorded. Experimental data obtained provide useful information for further theoretical study on such complicated fallure phenomenon. |
