Design Rules for calculating the strength of butt and fillet welded joints subject to Direct, Bending and Torsional loadings. Plus guidance on calculating centroids and second moment of area.
Just touch the F and B labels with the mouse pointer, don't click them.
• Basics A basic introduction into stress / strain relationships & weld design. • T Fillet Weld Formula for calculating the stresses in a fillet weld. • Lap Fillet Weld Formula for calculating the stresses in lap fillet welds subject to shear. • Cantilever Fillet welded cantilever subject to bending and shear • Lap Joint Subject To Torsion Fillet welded lap subject to Torsion and shear • Rectangular Block Subject To Torsion Rectangular and fillet welded and subject to Torsion • T Butt Weld Subject To Torsion Full Penetration T Butt welded Cantilever subject to Torsion • Lap Joint Subject To Bending and Shear This calculation method is one I came up with. Unfortunately I couldn't find a similar joint in any technical reference to verify it. • Back Ground Information Useful revision and helpful for understanding some of the above calculations. • Calculating Volume Using Solids Of Revolution I came across this method when I was trying to calculate the volume of a dished head on a pressure vessel and found it useful to know. • Bibliography Sources of my information and some useful references.
