Probably none of the above. I do not know of any way to simply "combine"
the yield strengths of two different materials. Typically, you would
look at the Emod of both materials, compute n, use that to convert the
area of the weakest material to be equivalent to that of the strongest
material, determine epsilon under the maximum load you expect to see,
and then convert that back to sigmas for both materials and then
determine if you have exceeded the yield strength of the weaker material.
