摘要：

The dynamic response of submarine structure at underwater explosion (UNDEX), which is significantly affected by the depth of water, is the basis of submarine safety design. Based on the protection of typical submarine structure in deep underwater explosion (D-UNDEX), the failure modes of the ring-stiffened convex cone-cylinder in D-UNDEX are studied. The D-UNDEX experiment with the maximum water depth of 500m was completed. The dynamic response process of convex cone-cylinder under various conditions was obtained by ABAQUS numerical simulation method. Based on the deformation and failure degree of the structure, three failure modes of ring-stiffened convex cone-cylinder were obtained, and the evolution and transformation processes of different failure modes were revealed. The results show that, with the increase in water depth and shock factor, the deformation and failure results of ring-stiffened convex cone-cylinder are more serious, and the evolution and transformation processes of failure mode are more complex. © 2021, Editorial Board of Acta Armamentarii.
