Angle of Internal Friction given Shear Strength of Cohesive Soil Solution

STEP 0: Pre-Calculation Summary

Formula Used

Angle of Internal Friction of Cohesive Soil = atan((Shear Strength-Unit Cohesion)/Normal Stress)
Φ_c = atan((τ_s-c_u)/σ_Normal)
This formula uses 2 Functions, 4 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
atan - Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle., atan(Number)

Variables Used

Angle of Internal Friction of Cohesive Soil - (Measured in Radian) - Angle of Internal Friction of Cohesive Soil is a measure of the shear strength of soil due to friction in cohesive soil.
Shear Strength - (Measured in Pascal) - Shear Strength is the strength of a material against structural failure when the material fails in shear.
Unit Cohesion - (Measured in Pascal) - Unit Cohesion is the shear strength of soil due to interparticle bonding and cementation.
Normal Stress - (Measured in Pascal) - Normal Stress is the stress component that acts perpendicular to the plane of interest within a soil mass or structure.

STEP 1: Convert Input(s) to Base Unit

Shear Strength: 1.2 Megapascal --> 1200000 Pascal (Check conversion here)
