What is Drucker-Prager Failure Criterion Explained about?

This document discusses the Drucker-Prager criterion for modeling failure in pressure-dependent materials. It presents equations that relate the constants of the Drucker-Prager model to the Mohr-Coulomb failure criteria. Specifically, it shows that the outer cone of the Drucker-Prager model circumscribes the hexagonal pyramid of the Mohr-Coulomb model, while the inner cone passes through the tension meridian. However, the document notes that neither cone may accurately capture the Mohr-Coulomb failure surfa
