1. What is Crushing Resistance of Plates per Pitch Length?

Definition: This calculator determines the crushing resistance of riveted plates per pitch length based on rivet diameter, number of rivets, plate thickness, and permissible compressive stress.

Purpose: It helps mechanical engineers and designers evaluate the strength of riveted joints against compressive forces.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P_c = d \times n \times t_1 \times \sigma_c \]

Where:

\( P_c \) — Crushing resistance (Newtons)
\( d \) — Diameter of rivet (meters)
\( n \) — Number of rivets per pitch
\( t_1 \) — Thickness of plate (meters)
\( \sigma_c \) — Permissible compressive stress (Pascals)

Explanation: The formula calculates the maximum compressive force the riveted joint can withstand before crushing failure occurs.

3. Importance of Crushing Resistance Calculation

Details: Proper calculation ensures joint integrity, prevents material failure, and helps in optimal rivet selection and spacing.

4. Using the Calculator

Tips: Enter the rivet diameter in meters, number of rivets per pitch, plate thickness in meters, and permissible compressive stress in Pascals. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What does ±5% tolerance mean?
A: It indicates the acceptable variation in input values that accounts for manufacturing tolerances and material inconsistencies.

Q2: How is rivet diameter measured?
A: It's the diameter of the rivet shank, typically matching the hole diameter before riveting.

Q3: What affects permissible compressive stress?
A: Material properties, temperature, and safety factors influence this value.

Q4: When would multiple rivets per pitch be used?
A: For higher load requirements or when single rivet strength is insufficient.

Q5: How does plate thickness impact resistance?
A: Thicker plates generally increase crushing resistance proportionally.
