A Unified Hardening Constitutive Theory for Soils: Fundamentals of Plasticity for Geomaterials provides a unified hardening (UH) theory capable of uniformly describing the behaviors of both sand and clay. The models developed within the UH theory framework are characterized by their simplicity and efficiency, requiring only a few parameters that have clear physical meanings. The book not only deepens the theoretical understanding of soil mechanics and related fields but also provides a practical reference for a wide range of civil engineering and geotechnical applications.

The insights and outcomes presented are important in terms of advancing theoretical knowledge and facilitating practical engineering solutions.
