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.
Strains oriented upon and transverse to fibers are related to stresses by means of equations:
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:
Now, we ...
