This research aims to analyze the dynamic behavior of steel plates subjected to explosive loading using both analytical and finite element models.
Developed the DYNABlast 1.1 analytical software for simulations of Kirchhoff plates under blast conditions.
Evaluated the performance of DYNABlast against numerical simulations from ABAQUS 6.14-1.
Considered geometric nonlinearity and immovable membrane effect in the analysis.
DYNABlast effectively simulated critical parameters such as displacements and stresses under explosive loading.
The comparison with ABAQUS confirmed the reliability of the DYNABlast model for analyzing explosive impacts.
Results highlighted the significance of the first fundamental mode in the energy concentration from explosions.
