1. What Is Constant 'b' For Inner Cylinder?

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

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

• \( b \) — Constant 'b' for inner cylinder
• \( \sigma_{\theta} \) — Hoop stress on thick shell (Pascal)
• \( a \) — Constant 'a' for inner cylinder
• \( r \) — Radius of cylindrical shell (Meter)

Explanation: This formula calculates the constant 'b' based on the hoop stress, constant 'a', and the radius of the cylindrical shell.

3. Importance Of Constant 'b' Calculation

Details: Accurate calculation of constant 'b' is essential for stress analysis in thick-walled cylinders, which is crucial in mechanical engineering applications such as pressure vessel design and pipeline engineering.

4. Using The Calculator

Tips: Enter hoop stress in Pascal, constant 'a', and radius in meters. All values must be valid (radius > 0).

5. Frequently Asked Questions (FAQ)
