Interfacial Behaviour of a Glued Bi-Material Structure - Recycled Beam and PZT Layer

In the presented paper the interface behavior of a glued intelligent bi-material structure composed of recycled concrete beam and piezoelectric material (PZT layer) is investigated. Closed form analytical solutions for the interfacial shear and peeling stresses are obtained for a given crack with initial length and located between the adhesive interface and PZT layers. A parametric analysis is done via MATHEMATICA 10.4 and specially developed programs. The analysis takes into account the effect of geometry, material characteristics and loading type on the structure behavior. A novelty of the work is the consideration of a combination between piezoelectric and recycled building materials. The combined material proves to be particularly suitable and useful for energy-efficient constructions. In addition, the programs designed enable one to find directly the quantities sought and facilitate the parametric analysis.
