DOI: 10.1016/j.ijimpeng.2019.103330
Abstract: Abstract This paper concerns the irreversible deformation and failure of metal plates to brief, but intense, dynamic (impulsive) load encountered in an air-blast. Hitherto, nearly all of the dynamic structural plasticity models of ‘fully-clamped’ plate… read more here.
