Results of parametric study samples.
| Sample | Initial drop acceleration (g) at 20 cm from the center of the slab | Impact load (kN) at initial drop | Initial concrete stress (MPa) in the drop impact zone | Initial drop displacement (mm) measured 20 mm from the bottom face center | Initial drop-induced residual displacement (mm) at a 20 mm offset from the center of the slab’s bottom face | Displacement (mm) at total failure beyond drop initiation position | DDE+ (J) upon reaching total failure | Max | Min | Top face | Bottom face |
