A Unified Two Independent Stress Variable Approach to Moisture-Change-Induced Unsaturated Soil Volume Change [PDF]
E3S Web of Conferences, 2023 In 1968, Matyas and Radhakrishna introduced the concept of the state surface, demonstrating that unsaturated soil volume change is dependent on two independent stress state variables, net total stress and suction.
