The goal of this article is to translate the stiffness of a vertical elements (column, wall, surface support) to a spring constant \"k\" which can be applied in the Y-direction in Diamonds.<\/p>\n\n\n\n

For a column<\/h2>\n\n\n\n

With Hooke’s Law \"F=k \cdot \Delta x\" and the formula for stress \"\sigma=\frac{F}{A}\", a formula for the spring constant can be deducted. This formula assumes that the element is supported at the buttom.

  <\/span>   <\/span>\"\[k=\frac{F}{\Delta x} = \frac{\sigma A}{\Delta x} = \frac{E \varepsilon A}{\Delta x} = \frac{E (\Delta x /l) A}{\Delta x} = \frac{E A}{l}\]\"<\/p>
