On the some advances in studies of structural dynamic plastic failure. (Chinese. English summary) Zbl 0919.73177
Summary: This paper presents recent advances in the studies of dynamic plastic failure of commonly used engineering structural elements (such as beams, plates, cylindrical shells, circular rings, and structures of sandwich or composite materials), subjected to short but large dynamic loads. The failure modes of such structural elements are of universal significance. It is suggested that a nondimensional number (the damage number) can be used to represent a universal failure criterion for different failure modes. Ocean platform and bar structures are taken as two examples.
