![]() Essentially, the load will sweep over the surface with no impeding objects. This indicates where blast load travels parallel to a surface rather than perpendicular. The side-on blast load (also called free-field blast load) includes the subscript "so" used commonly throughout literature. Notice there are two different curves represented in the idealized pressure-time history diagram including the "side-on blast load" and the "reflected blast load" indicated by the dashed line and solid line, respectively. The time period following the positive phase where pressure falls below atmospheric pressure. The total pressure-time energy applied during the positive duration calculated by the area under the curve. The time period for the pressure to return to ambient. The instantaneous pressure arriving at the structure above the ambient atmospheric pressure.
