Earth Soil Weight

Overview

Engineering reference data for Earth Soil Weight in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Soil Volume Formulas

The void ratio $e$ is the ratio of the volume of voids to the volume of solids: $e = \frac{V_v}{V_s} = \frac{n}{1 - n}$

Porosity $n$ is the ratio of the volume of voids to the total volume: $n = \frac{V_v}{V} = \frac{e}{1 + e}$

The degree of saturation $S$ is the ratio of the volume of water to the total volume: $S = \frac{V_w}{V}$ where $V_v = V_a + V_w$ is the volume of voids, $V_s$ is the volume of solids, $V$ is the total volume, and $V_w$ is the volume of water.
