Crimped vs Soldered and Crimped Wire Terminals

Do you have any intention of testing non-axial loads? I’d be interested to see how each type fares when the terminal and wire are in shear.

I’ll respond to your question with a question: what would you expect to learn from a shear test?

I’d personally expect it to better test how solder effects the stiffness of the joint versus crimping. In theory a stiffer joint could potentially mean higher stress on the copper strands, at least in my mind.

There is no need to test this because the body of evidence from multiple sources indicate that soldering does increase stress on the terminal vs crimping .

Soldering invariably flows down the wire (how far is up to the skill of the operator, but it always flows a little). This creates a larger moment arm for the wire to pull on the terminal thus creating more stress.

So, your mental model is probably correct.
