Poroelasticity - Fundamentals and Applications

Learn the theory and applications of poroelasticity for quasi-static subsurface engineering applications through this comprehensive video playlist. Master the fundamental equations that govern porous media behavior, including applications to bone and cement paste beyond traditional subsurface materials. Explore the theoretical formulation based on Oliver Coussy's "Mechanics and Physics of Porous Solids" while examining practical problems and real-world applications drawn from current literature and research. Understand the relationship between bulk strain, solid strain, and porosity strain in porous solids, then delve into fundamental poroelasticity equations and key poroelastic parameters. Discover methods for both indirect determination and direct measurement of the Biot coefficient, and explore how poroelasticity extends beyond simple effective stress equations. Analyze poroelastic drained solutions for in-situ stress and depletion-related changes, study the pore pressure diffusivity equation for fluid flow coupled with poroelasticity, and examine undrained loading scenarios including pore pressure changes, undrained bulk modulus, and Skempton coefficient calculations. Apply your knowledge through practical workshops focusing on Biot coefficient determination and horizontal stress prediction after depletion, building expertise in this critical field that bridges mechanics and physics of porous materials.
