ANALYSIS OF THE LIMITING STATE OF CYLINDRICAL SHELLS WITH CRACKS WITH REGARD FOR THE CONTACT OF CRACK LIPS

摘要

We study the stress-strain state and limiting equilibrium of cracked cylindrical shells. The effect of crack closure caused by bending strains is taken into account according to the model of contact of crack lips along a line. By using the energy fracture criterion, we plot the diagrams of limiting equilibrium for any ratio of tensile and bending loads.
