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