Interfacial debonding of a piezoelastic bi-material structure applicable for wind rotor blades.
In: Mechanics of Advanced Materials and Structures,
Artikel, Bibliographie
Kurzbeschreibung (Abstract)
The main goal of the paper is to model the straight line part of a wind blade by an analytical 1-D shear lag model in order to analyze and detect possible interface delamination through the change of the voltage along the interface. A unit cell presented by a bi-material structure consisting in a first piezoelastic layer and an elastic second layer under static mechanical and electric load is considered. Numerical examples are provided and illustrated by figures and discussed. A criterion for detecting the interface elastic-brittle delamination and a safety zone for combined electrical and static loading is proposed.
