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