1. What is Thickness of Plates given Crushing Resistance?

Definition: This calculator determines the required thickness of plates in a riveted joint based on the crushing resistance, rivet diameter, number of rivets, and permissible compressive stress.

Purpose: It helps mechanical engineers and designers ensure that plates in riveted joints have sufficient thickness to withstand crushing forces.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ t1 = \frac{Pc}{d \times n \times \sigma c} \]

Where:

\( t1 \) — Thickness of plate (meters)
\( Pc \) — Crushing resistance of riveted plate per pitch (Newtons)
\( d \) — Diameter of rivet (meters)
\( n \) — Number of rivets per pitch
\( \sigma c \) — Permissible compressive stress of riveted plate (Pascals)

Explanation: The crushing resistance is divided by the product of rivet diameter, number of rivets, and permissible stress to determine the minimum required plate thickness.

3. Importance of Plate Thickness Calculation

Details: Proper thickness calculation prevents plate failure due to crushing, ensures joint integrity, and maintains safety factors in mechanical designs.

4. Using the Calculator

Tips: Enter the crushing resistance, rivet diameter, number of rivets per pitch, permissible compressive stress, and tolerance percentage. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is crushing resistance in riveted joints?
A: It's the force that causes compressive failure of the plate material between rivets.

Q2: How does rivet diameter affect plate thickness?
A: Larger rivet diameters distribute force over more area, potentially allowing thinner plates.

Q3: Why include a tolerance percentage?
A: Manufacturing variations require a tolerance range (±5% is typical) for practical applications.

Q4: What's a typical permissible compressive stress?
A: For mild steel plates, it's typically around 94 MPa (94,000,000 Pa), but varies by material.

Q5: How do I determine crushing resistance?
A: It's calculated based on expected loads and safety factors for your specific application.
