1. What is the Thickness of Member under Compression Formula?

The formula calculates the thickness of member under compression in a gasket joint assembly. It depends on the nominal bolt diameter, modulus of elasticity, and approximate stiffness of the gasketed joint.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ t = \frac{\pi \times d^2}{4} \times \frac{E}{K} \]

Where:

\( t \) — Thickness of Member under Compression (m)
\( d \) — Nominal Bolt Diameter on Cylinder (m)
\( E \) — Modulus of Elasticity for Gasket Joint (Pa)
\( K \) — Approximate Stiffness of Gasketed Joint (N/m)
\( \pi \) — Archimedes' constant (≈3.14159)

Explanation: The formula calculates the required thickness based on the cross-sectional area of the bolt and the ratio of elasticity to stiffness.

3. Importance of Thickness Calculation

Details: Accurate thickness calculation is crucial for ensuring proper sealing performance, preventing leakage, and maintaining structural integrity in gasketed joint assemblies.

4. Using the Calculator

Tips: Enter nominal bolt diameter in meters, modulus of elasticity in Pascals, and approximate stiffness in N/m. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect the thickness calculation?
A: The thickness depends on bolt diameter, material elasticity, and joint stiffness characteristics.

Q2: Why is modulus of elasticity important?
A: Modulus of elasticity determines how much a material will deform under stress, which affects the compression behavior.

Q3: What is approximate stiffness of gasketed joint?
A: It represents the force required to deform the joint assembly per unit length, indicating the joint's resistance to compression.

Q4: When is this calculation typically used?
A: This calculation is used in mechanical engineering for designing bolted flange connections with gaskets in pressure vessels and piping systems.

Q5: Are there limitations to this formula?
A: This formula provides an approximate calculation and may need adjustment based on specific material properties, joint configuration, and operating conditions.
