摘要: Abstract Experimental and numerical results for fully built-in stiffened square plates subjected to blast pressure loading are presented. The strain rate-sensitive exhibit mode I (large ductile deformation) II (tensile tearing) failure as the load intensity increases. analysis is carried out using a finite element formulation which incorporates non-linear geometry material effects well rate sensitivity. Mode predicted both maximum deflection deformation shape. Initiation of by criterion, but limited data insufficient conformation.
