Implications of the principle of effective stress

Gerd Gudehus

Summary: This passage provides a detailed description of the principle of effective stress and its application in soil and rock, focusing on the explanation of shear strength in water-saturated soil and over-consolidated clay, as well as the neutrality related to pore water pressure pw. It also mentions the interaction between solid fabric and pore water determined by the pw-neutrality of the solid mineral, while discussing the controversial nature of numerical models due to fractal features.

Theory of Effective Stress in Soil and Rock and Implications for Fracturing Processes: A Review

Vincenzo Guerriero et al.

Summary: The effective stress principle (ESP) is crucial in geology and engineering, involving strain and failure of various materials. Despite being theoretically derived since the 1920s, understanding of ESP-related topics by some in the scientific community is incomplete. This review aims to provide updated guidance on theoretical and experimental approaches to ESP over the past century, especially in relation to geological fracturing processes, illustrating the basic theory behind ESP, discussing ESP-related theories and experimental results, and revisiting classical works to derive a rigorous ESP proof.
