Abstract

This entry presents the theoretical fundamentals, the mathematical formulation, and the
numerical solution for the problem of desiccation cracks in clayey soils. The formulation uses two
stress state variables (total stress and suction) and results in a non‐symmetric and nonlinear system
of transient partial differential equations. A release node algorithm technique is proposed to simulate
cracking, and the strategy to implement it in the hydromechanical framework is explained in
detail. This general framework was validated with experimental results, and several numerical examples
were published at international conferences and in journal papers.
