Mohr-Coulomb Failure Analysis of Triaxial Tests on Soil | How to Obtain Cohesion and Friction Angle

Mohr-Coulomb failure criterion is used to determine the strength of soil. This video explains how to use the data from three triaxial tests, draw a Mohr circle for each test, and obtain the failure envelope using the Mohr-Coulomb failure criterion that defines the soil strength such as cohesion and friction angle. These three tests were taken from real experiments and as you will see in this video, they don't match perfectly along the failure envelope line which is pretty common in real practice.
