Coefficient of Internal Friction for Soil Solution

STEP 0: Pre-Calculation Summary

Formula Used

Coefficient of Internal Friction = (Shear Force on Soil/Total Normal Force)
tanφ = (F_s/P)
This formula uses 3 Variables

Variables Used

Coefficient of Internal Friction - Coefficient of Internal Friction is a measure of the ability of a unit of rock or soil to withstand shear stress.
Shear Force on Soil - (Measured in Newton) - Shear Force on Soil is the force which causes shear deformation to occur in the shear plane in soil mechanics.
Total Normal Force - (Measured in Newton) - Total normal force acting at the base of the slice.

STEP 1: Convert Input(s) to Base Unit

Shear Force on Soil: 48.5 Newton --> 48.5 Newton No Conversion Required
Total Normal Force: 150 Newton --> 150 Newton No Conversion Required

STEP 2: Evaluate Formula

What is Coefficient of Internal Friction?

The magnitude of the shear stress that causes failure in a material subjected to no normal stress is related to the materials cohesive strength.The slope of the Mohr failure envelope is the ratio of the shear stress to the normal stress at failure. This ratio is termed the coefficient of internal friction.

How to Calculate Coefficient of Internal Friction for Soil?

Coefficient of Internal Friction for Soil calculator uses Coefficient of Internal Friction = (Shear Force on Soil/Total Normal Force) to calculate the Coefficient of Internal Friction, The Coefficient of Internal Friction for Soil is defined as the ratio of the shear stress to the normal stress at failure. Coefficient of Internal Friction is denoted by tanφ symbol.

How to calculate Coefficient of Internal Friction for Soil using this online calculator? To use this online calculator for Coefficient of Internal Friction for Soil, enter Shear Force on Soil (F_s) & Total Normal Force (P) and hit the calculate button. Here is how the Coefficient of Internal Friction for Soil calculation can be explained with given input values -> 0.323333 = (48.5/150).
