The study aims to analyze how explosive loading affects the dynamic behavior of steel plates, emphasizing the influence of the negative pressure phase.
Utilized Kirchhoff's theory to model the behavior of simply supported steel plates.
Incorporated geometric nonlinearity through the effect of a laterally immovable membrane.
Calibrated explosive loading using DYNABlast software and performed finite element simulations in ABAQUS.
Conducted parametric dynamic analyses using various loading types and explosive masses.
Negative pressure phases were found to significantly influence structural displacements and stresses.
Considerable effects were observed at scaled distances greater than 8 m/kg^1/3.
Dynamic analyses revealed differences in structural behavior depending on the specific loading scenarios applied.
