    Bead Strength
Click For Summary
Calculating weld bead strength requires a clear understanding of shear stress and the forces acting on the weld. The discussion highlights the need for clarification on the orientation of angle beta in relation to the xy plane. There is confusion regarding the use of shear force to compute normal stress, specifically the calculation of alphay using cos(beta). Participants emphasize the importance of accurately depicting the applied forces and moments in a sketch to better analyze the joint loading. A precise representation of the assembly will aid in understanding the weld strength calculations.

I am looking into calculating the weld bead strength. I am unsure of calculating the shear stress..the attachment has a drawing..any help is appreciated

vanuta: (1) Is angle beta in the xy plane? Or not in the xy plane?

(2) Why do you call alphay a normal stress, when it looks like you are using a shear force, F*cos(beta), to compute alphay?

(3) Why do you use cos(beta) to compute alphay?

(4) I am not yet confident that you have drawn the applied force, F, as it really occurs on the real assembly. Please draw a correct, quick, freehand sketch of the assembly, showing how and where the applied force(s), such as F, are really applied. And show the x, y, and z dimensions to the point of application of the applied force(s) (and applied moment(s), if any), so that we can really see how your joint is loaded.
 

Thread 'What mathematics software should engineering students use?'

What mathematics software should engineering students use? Is it correct that much of the engineering industry relies on MATLAB, making it the tool many graduates will encounter in professional settings? How does SageMath compare? It is a free package that supports both numerical and symbolic computation and can be installed on various platforms. Could it become more widely used because it is freely available? I am an academic who has taught engineering mathematics, and taught the...
