Debonding criterion for the piezoelectric fibre push-out test [PDF]

Philosophical Magazine Letters, 2006
A theoretical model of piezoelectric fibre push-out is developed within the framework of a modified shear-lag theory to study stress and electrical field transfer. Based on the model, a debonding criterion for the piezoelectric effect is presented utilizing a fracture-mechanics approach to investigate the debonding process of piezoelectric fibre in the

A finite element analysis of the push‐out test: Influence of test conditions [PDF]

Journal of Biomedical Materials Research, 1992
AbstractThe commonly used method for quantitative evaluation of the strength of a bone‐implant interface is the push‐out test. In order to give an impulse to standardization and to gain more insight in the biomechanics of the push‐out test, a finite element analysis of this test was performed.

Influence of micro‐structure on fibre push‐out tests [PDF]

PAMM, 2011
AbstractIn fibre reinforced materials, the interface toughness has a significant influence on strength and damage resistance. Especially in discontinuous fibre reinforced composites, where high densities of fibre ends are apparent, it has been shown that additives which improve the interfacial toughness can increase the effective strength of the ...
