How to determine stress distrubution in overlap welds in tension

[jamesabc]

I am looking to determine stress distrubution is overlap welds with some samples which have been tensile tested in a tensile testing machine. i want to find where there is the highest stress concentrations etc. how can i do this?

Just to clarify, when you say overlapping, are you describing the joint configuration or the fact that the welds are overlapping, i.e. multiple passes?

joint configuration. one plate is placed over the other and lap welded.
