    Abstract
  • The dynamic response of a cabin model under an internal explosion load is explored and the structural responses of clamped square plates under explosion loads are analyzed using dimensional analysis. A dimensionless number for the deflection-thickness ratio of the clamped square plates is proposed and the influence of the explosive energy Qm, thickness H, and yield strength σ0 of the square plates are considered in the dimensionless number. A dimensionless relationship diagram between the deflection-thickness ratio and dimensionless number is provided. It can be concluded that there is a linear relationship between the deformation of the clamped square plates and Qm/H3σ0 under explosion loads. The dimensionless number can be applied in dynamic response experiments on cabin structures under explosion loads and used to predict the final plastic deformation of structures.
