Hooke's Law of a Composite Lamina |

The constitutive equations describe how the stresses and straines relate within each lamina (Hooke's law). Detailed discussion can be found in the following sections: stress-strain relations of materials, stress-strain relations of lamina for principal directions, coordinate transformation of lamina for arbitrary orientation, and stress-strain relations of lamina for arbitrary orientation. For a single lamina of any orientation, where and [ Conversely, where and [ The coordinate transformation matrix is and the angle is illustrated below |

Hooke's Law of a Lamina within Laminated Composites |

For a single lamina of any orientation within a laminated composite plate, the same relations apply. Let the subscript and, |
