Are you defining function for the epsilons on purpose or are they supposed to be simple variables (vectors)?

 

My guess is that you don't want functions but just vectors of values.

See the attached file which also changes back the functions

we defined for sigma.xx etc. back to vectors.

I suppose it's about this part:

Which appears to be a good solve block. Now the variable that you want to Find, is not in the expression between Given and Find, as there are only k and sigma variables in the expression, lambda isn't there. So mathcad will not know how to find it. I can see, above the solve block, that the k and sigma variables may depend upon the lambda that you want to find, but Mathcad doesn't know, or better said, has forgotten that.

To remedy this situation, you can change these k and sigma variables into functions of one (at least the lambda parameter you intend to find) or more parameters.

 

Success!

    I don't know what you wrote. Would you create sample?

    See if the attached file helps.

    I turned the sigma.. into functions of lambda and index i and the solve block into a function of the index i.

    No solution is found for index i=1.
