1. What Is The Allowable Tensile Stress Given Tensile Strength Of Double Fillet Lap?

Allowable tensile stress is the maximum stress that a double fillet lap weld can safely withstand under tensile loading conditions. It is derived from the tensile strength of the weld material, considering the geometry of the weld.

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

• \( \sigma_t \) — Allowable tensile stress (Pa)
• \( TS \) — Tensile strength (Pa)
• \( l \) — Length of weld (m)
• \( t_{plate} \) — Thickness of plate (m)

Explanation: The formula calculates the allowable tensile stress by dividing the tensile strength by the product of 1.414, weld length, and plate thickness.

3. Importance Of Allowable Tensile Stress Calculation

Details: Accurate calculation of allowable tensile stress is essential for ensuring the structural integrity and safety of welded joints under tensile loads.

4. Using The Calculator

Tips: Enter tensile strength in pascals (Pa), length of weld in meters (m), and thickness of plate in meters (m). All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is tensile strength?
A: Tensile strength is the maximum stress that a material can withstand while being stretched or pulled before breaking.

Q2: Why is the factor 1.414 used in the formula?
A: The factor 1.414 (√2) accounts for the geometry of the double fillet lap weld, considering the effective throat area.

Q3: What units should be used for input values?
A: Use consistent units: pascals (Pa) for tensile strength, and meters (m) for length and thickness.

Q4: Can this calculator be used for single fillet welds?
A: No, this formula is specifically designed for double fillet lap welds. Different formulas apply to single fillet welds.

Q5: What safety factors should be considered?
A: Always apply appropriate safety factors based on industry standards and specific application requirements to ensure safe design.
