1. What is Constant 'b' for Inner Cylinder?

Constant 'b' for inner cylinder is defined as the constant used in Lame's equation for compound cylinders. It helps in determining the stress distribution in thick-walled cylinders under pressure.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( b \) — Constant 'b' for inner cylinder
• \( P_v \) — Radial pressure at the junction (Pascal/m²)
• \( a \) — Constant 'a' for inner cylinder (unitless)
• \( r \) — Radius at the junction (meters)

Explanation: This formula calculates the constant 'b' which is essential in Lame's equations for determining stress distributions in compound cylinders.

3. Importance of Constant 'b' Calculation

Details: Accurate calculation of constant 'b' is crucial for proper stress analysis in compound cylinders, which is essential for mechanical design and pressure vessel applications.

4. Using the Calculator

Tips: Enter radial pressure in Pascal/m², constant 'a' (unitless), and radius at junction in meters. All values must be valid (radius > 0).
