 Unified strength theory

Unified Strength Theory (UST) is a theoretical framework used in materials science and engineering to predict the failure of materials under various loading conditions. It seeks to provide a comprehensive approach to understanding how materials behave when subjected to different types of stress, including tensile, compressive, and shear stress. The main goal of Unified Strength Theory is to unify different failure criteria that have been developed for specific types of materials or loading conditions into a single, cohesive theory.
