ច្បាប់ហ៊ូក៖ ភាពខុសគ្នារវាងកំណែនានា

ដែល៖

:- <math> \sigma_{ij} </math> = កុងត្រាំង

:- <math> \nu </math> = មេគុណ [[Poisson]]

ទំរង់បញ្ចេញរបស់ច្បាប់នេះគឺៈ

:<math> \varepsilon _{11} = \frac {1} {E} \left( \sigma_{11} - \nu \left( \sigma_{22} + \sigma_{33} \right) \right)</math> , <math>\varepsilon _{22} = \frac {1} {E} \left( \sigma_{22} - \nu \left( \sigma_{11} + \sigma_{33} \right) \right)</math> ,<math>\varepsilon _{33} = \frac {1} {E} \left( \sigma_{33} - \nu \left( \sigma_{11} + \sigma_{22} \right) \right)</math>, <math>\varepsilon _{12} = \frac {1 + \nu} {E} \sigma _{12}</math> , <math>\varepsilon _{13} = \frac {1 + \nu} {E} \sigma _{13}</math> , <math>\varepsilon _{23} = \frac {1 + \nu} {E} \sigma _{23}</math>
