Virtual Duration of Positive Pressure Action (Triangule Calculation)

2012, Teich, Interaction of explosions with flexible structures (2.51)

{\tilde{t}}_{d} = \frac{2 \cdot i^{+}}{{\hat{p}}_{10}}

t^~_d	Virtual duration of the positive pressure action
i⁺	Positive specific momentum [kPa ms]
p₁₀	Maximum peak overpressure of remote explosion (Kinney & Graham) [kPa]
