Radial Displacement Spherical (Radius Change) Formula

\(\large{ \Delta_r = \frac{ p \; r^2 \; \left( 1 \;-\; \mu  \right)  }{ 2 \; \lambda \; t }   }\)
 Symbol English Metric
\(\large{ \Delta_r }\) = radius change \(\large{ in }\) \(\large{ mm }\)
\(\large{ p }\) = pressure under consideration \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ r }\) = radius to point of intrest \(\large{ in }\) \(\large{ mm }\)
\(\large{ \mu }\)  (Greek symbol mu) = Poisson's Ratio \(\large{ dimensionless }\)
\(\large{ \lambda }\)  (Greek symbol lambda) = elastic modulus \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ t }\) = wall thickness \(\large{ in }\) \(\large{ mm }\)
