Radial Displacement Thin-wall Section (Open Ended)

Radial Displacement Thin-wall Section (Open Ended) Formula
\( \Delta_r \;=\; \dfrac{ p \cdot r^2 }{ \lambda \cdot t }\)
Symbol	English	Metric
\( \Delta_r \) = Radius Change	\( in \)	\( mm \)
\( p \) = Pressure Under Consideration	\(lbf\;/\;in^2\)	\(Pa\)
\( r \) = Radius to Point of Intrest	\( in \)	\( mm \)
\( \lambda \) (Greek symbol lambda) = Elastic Modulus	\(lbf\;/\;in^2\)	\(Pa\)
\( t \) = Wall Thickness	\( in \)	\( mm \)
