Hooke's Law |

The constitutive equation describes how the stresses and straines are related within the plate (Hooke's law). In The compliance (stress to strain) form is The stiffness (strain to stress) form is Note that the stresses and strains are functions of |

Constitutive Equation of Classical Plates Materials |

Based on the kinematics of classical plates, the stress-strain relations can be simplified to alternatively, they can be written as and which yields |
