Thickness of Plate Formula:
Definition: This calculator determines the required thickness of plates based on the load carried by parallel fillet welds, shear stress, and weld length.
Purpose: It helps engineers and designers ensure proper plate thickness for welded joints under specific loading conditions.
The calculator uses the formula:
Where:
Explanation: The formula calculates the minimum plate thickness required to safely carry the applied load through the parallel fillet welds.
Details: Proper plate thickness ensures structural integrity, prevents weld failure, and maintains safety margins in welded connections.
Tips: Enter the load on weld in Newtons, shear stress in Pascals, length of parallel fillet weld in meters, and tolerance percentage (default ±5%). All values must be > 0.
Q1: What is the 1.414 factor in the formula?
A: The 1.414 (√2) factor accounts for the 45° throat dimension in fillet welds.
Q2: How do I determine the shear stress value?
A: Shear stress is typically 60% of the tensile strength of the weld material or base metal, whichever is weaker.
Q3: What's a typical tolerance for plate thickness?
A: ±5% is common, but this may vary based on manufacturing capabilities and design requirements.
Q4: Does this consider safety factors?
A: No, the calculated thickness is theoretical. Apply appropriate safety factors based on your design codes.
Q5: Can I use this for other weld types?
A: This formula is specific to parallel fillet welds. Other weld configurations require different calculations.
