This book offers a comprehensive and structured exploration of the mechanical behavior of heterogeneous geomaterials using micromechanics and homogenization theory, guiding readers from fundamental concepts to advanced multiscale constitutive modeling. It develops rigorous theoretical foundations, presents original contributions such as new yield criteria for porous and multiphase materials, and demonstrates how these concepts can be applied to complex geomaterials like concrete and argillite. By replacing empirical approaches with a physically grounded framework, the book provides powerful tools for understanding and predicting material behavior, making it a valuable resource for researchers, graduate students, and engineers in geomechanics, civil engineering, petroleum engineering, and solid mechanics.
Establishes a rigorous link between microscale features and macroscale mechanical behavior of heterogeneous geomaterials Provides a systematic, micromechanics-based framework for deriving microstructure-informed strength and yield criteria Bridges theory and application through practical multiscale constitutive models for real engineering materials
