Radial Displacement Spherical (Radius Change) Formula
\( \Delta_r \;=\; [\; (p \; r^2 ) \; ( 1 - \mu ) \;] \;/\; [\; 2 \; \lambda \; t \;] \)
Symbol	English	Metric
\( \Delta_r \) = Radius Change	\( in \)	\( mm \)
\( p \) = Pressure Under Consideration	\(lbf\;/\;in^2\)	\(Pa\)
\( r \) = Radius to Point of Intrest	\( in \)	\( mm \)
\( \mu \) (Greek symbol mu) = Poisson's Ratio	\( dimensionless \)	\( dimensionless \)
\( \lambda \) (Greek symbol lambda) = Elastic Modulus	\(lbf\;/\; in^2\)	\(Pa\)
\( t \) = Wall Thickness	\( in \)	\( mm \)
