This calculator determines the radius of a cylindrical shell under internal fluid pressure using Lame's equation for thick-walled cylinders. It calculates the radial position where the stress components are evaluated in pressure vessel design.
The calculator uses the formula:
Where:
Explanation: This formula calculates the radius at a specific point in the thick-walled cylinder where the radial stress is being evaluated under internal fluid pressure conditions.
Details: Accurate radius calculation is crucial for pressure vessel design, stress analysis, and ensuring structural integrity under internal pressure conditions. It helps engineers determine critical stress points in thick-walled cylinders.
Tips: Enter the constant B value, radial pressure in Pascal per Square Meter, and constant A value. All values must be valid (constant B > 0, radial pressure ≥ 0).
Q1: What is Lame's equation used for?
A: Lame's equation is used to calculate stresses in thick-walled cylinders subjected to internal and/or external pressure.
Q2: When is this calculation particularly important?
A: This calculation is critical in pressure vessel design, piping systems, and any application involving thick-walled cylinders under internal fluid pressure.
Q3: What are the typical units for these calculations?
A: Radial pressure is typically measured in Pascal per Square Meter, constants are dimensionless, and radius is measured in meters.
Q4: Are there limitations to this formula?
A: This formula assumes homogeneous, isotropic material and applies specifically to thick-walled cylinders with internal fluid pressure only.
Q5: How does wall thickness affect the results?
A: Thicker walls generally result in lower stress concentrations but require more precise radius calculations for accurate stress analysis.
