Explanation:

Classic Laminate Theory: how to derive the reduced stiffness...

• Then, using basic concepts of Strength of Materials and Continuum Mechanics, the stress tensor can be written as follows:

• Hence, when i=1 and j=1, the stress in direction 11′ should be:

• Following the same approach, the stress in direction 22′ can be obtained when i=2 and j=2:
