1. What is Shear Stress in Transverse Fillet Weld?

Shear stress in transverse fillet weld is the force tending to cause deformation of the fillet weld by slippage along a plane or planes parallel to the imposed stress. It represents the internal resistance of the weld material to shearing forces.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \tau = \frac{P_d \cdot \sin(\theta) \cdot (\sin(\theta) + \cos(\theta))}{h_l \cdot L} \]

Where:

\( \tau \) — Shear stress in transverse fillet weld (Pa)
\( P_d \) — Load on double transverse fillet weld (N)
\( \theta \) — Weld cut angle (rad)
\( h_l \) — Leg of weld (m)
\( L \) — Length of weld (m)

Explanation: This formula calculates the shear stress induced in a plane that is inclined at angle θ to the horizontal in a double transverse fillet weld.

3. Importance of Shear Stress Calculation

Details: Accurate shear stress calculation is crucial for weld design and structural integrity assessment. It helps engineers determine if a weld can withstand applied loads without failure and ensures safety in welded structures.

4. Using the Calculator

Tips: Enter load in newtons (N), weld cut angle in radians, leg of weld in meters, and length of weld in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a transverse fillet weld?
A: A transverse fillet weld is a type of weld where the direction of welding is perpendicular to the direction of the applied force.

Q2: Why is the angle θ important in this calculation?
A: The angle θ determines the inclination of the plane where shear stress is being calculated, which affects the magnitude and distribution of stress in the weld.

Q3: What are typical values for weld leg length?
A: Weld leg lengths typically range from 3mm to 25mm depending on the material thickness and application requirements.

Q4: How does this formula differ from other weld stress formulas?
A: This specific formula accounts for the inclination angle θ of the plane, making it suitable for calculating shear stress on inclined planes in transverse fillet welds.

Q5: What safety factors should be considered in weld design?
A: Typical safety factors range from 1.5 to 4.0 depending on the application, material properties, and consequences of failure.
