    Problem 1: (Question 5)

    An orthotropic lamina has fibers oriented at 45. It is subjected to strains x and xy given by: x = 0.001 and xy = 0.001.
    Determine the maximum and minimum values that y can take such that the lamina does not fail according to Maximum Stress Theory.

    Data:

    Solution:
    Strains oriented upon and transverse to fibers are related to stresses by means of equations:
    ( 19)
    Since we have to apply the maximum stress theory as failure criterion, we need to solve the above equations in 1 , 2 , 12 .and afterwards to apply (1).
    By solving the linear algebraic system (19), we get:
    ( 20)
    Now, we ...
