1. What is Allowable Tensile Stress in Plate?

Definition: This calculator determines the allowable tensile stress in a plate based on the tearing strength of rivets, rivet pitch, diameter, and plate thickness.

Purpose: It helps mechanical engineers and designers ensure plate materials can withstand the stresses caused by riveted connections.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \sigma_t = \frac{T_{strength}}{(p - D_{rivet}) \times t_{plate}} \]

Where:

\( \sigma_t \) — Tensile stress (Pascal)
\( T_{strength} \) — Tearing strength (Newtons)
\( p \) — Pitch of rivet (meters)
\( D_{rivet} \) — Rivet diameter (meters)
\( t_{plate} \) — Thickness of plate (meters)

Explanation: The tearing strength is divided by the effective area between rivets to determine the stress.

3. Importance of Tensile Stress Calculation

Details: Proper calculation ensures structural integrity, prevents material failure, and helps in selecting appropriate materials and dimensions.

4. Using the Calculator

Tips: Enter all required dimensions in meters. The tolerance field (default ±5%) can be adjusted for safety factors.

5. Frequently Asked Questions (FAQ)

Q1: What is tearing strength?
A: Tearing strength is the force required to start or continue tearing a material under specified conditions.

Q2: Why is pitch minus diameter used?
A: This calculates the effective load-bearing width between rivets where stress concentrates.

Q3: What's a typical rivet pitch?
A: Pitch typically ranges from 2.5 to 4 times the rivet diameter, but depends on application.

Q4: How does plate thickness affect stress?
A: Thicker plates reduce stress for the same load, as the load is distributed over more material.

Q5: When should I adjust the tolerance?
A: Increase tolerance for safety-critical applications or when material properties vary.
