Advanced numerical modelling of slab-subgrade interaction with uplift using an augmented Lagrangian Mortar FEM approach

Accurate representation of slab–subgrade interaction under partial contact is essential for evaluating rigid pavement response. This study develops an Augmented Lagrangian Mortar Finite Element Method (AL-MFEM) for modelling unilateral slab–subgrade contact and separation, combin...
