Abstract: | A theoretical model is presented to study the elastic deformation process and frictional sliding behavior in single piezoelectric
fibre push-out tests. Based on the theoretical model and some necessary simplifications, stress and electric fields are obtained
for push-out tests of a circular piezoelectric fibre embedded in an elastic matrix. Numerical results of a piezoelectric fibre/expoxy
matrix system are presented to verify the proposed formulation. The study shows that there is a significant effect of the
piezoelectric parameter and embedded fibre length on stress transfer, electric field distribution and load-displacement curve
of the frictional sliding process. This study also indicates that the piezoelectric effect has a distinct influence on the
mechanical behavior and properties of the interface in a fibre/matrix system. |
