Coupling elastic models through interfacial conditions with application to concrete pavement overlays

摘要

A simple mathematical model accompanied with a validation is presented to capture the deformation behavior observed in laboratory tests involving overlayed concrete samples. The model presented is based on linear elasticity in which the layers are conceptually envisioned as Mindlin plates overlaying one another while resting of a Winkler-type foundation. The interfacial conditions involve a coupling between the plates through elastic conditions satisfied by their relative displacements. Experimental validation is conducted on samples using analogous Timoshenko beam models.
