As an exercise, I am comparing simulation results of a simple fillet weld attaching a pipe to a plate.
The Simulation FEA results seem to be much more conservative than hand calcs from Blodgett - Design of Weldments.
Hand calcs = 0.058"
FEA = 0.208"
See below comparisons. Does anyone see anything amiss in my set up?
I am assuming the E70 (SUTS = 70 ksi) electrode is divided by the safety factor of 3.
Note: In the FEA, the pipe wall thickness is 0.25" and the plate thickness was considered to be 10" x 10" x 2" thick (rigid).
