Duration of Positive Pressure Action

2012, Teich, Interaction of explosions with flexible structures (2.30)

t_{d} = \frac{i^{+}}{{\hat{p}}_{10}} \cdot (\frac{α^{2}}{α - 1 + e^{- α}})

t_d	Duration of the positive pressure action
i⁺	Positive specific momentum [kPa ms]
p₁₀	Maximum peak overpressure of remote explosion (Kinney & Graham) [kPa]
α	Shape factor
e	Euler's number
