Practice Problem 5
A laminate is subjected to some unknown in-plane loading conditions. The total thickness of the
laminate is measured to be 32 mm . The laminate stiffness matrices are given below.
As a result of this in-plane loading, the curvatures are constants throughout the laminate, and the
in-plane strains are measured at a point that is located 6 mm from the top of the laminate and are
found to be:
-\epsi _(x)=\epsi _(y)=3.5\times 10^(-6)
\gamma _(s)=1.25\times 10^(-5)
\kappa _(x)=\kappa _(y)=1.5\times 10^(-4)m^(-1)
\kappa _(s)=0
