Examples:

Note: In the following examples, each lamina has a thickness of 1 mm and material is AS4/3501-6 Epoxy from Soden et al [4].

Example 5.8: For the laminate in Example 5.2 (that is, ), find the effective in-plane and flexural laminate engineering constants.

Solution: This is a symmetric matrix. Hence, . A and D matrices are given as:

Now we have

Thus, we can find the in-plane laminate engineering constants as

Now,

Now, we calculate the flexural engineering constants as
