Micromechanical analysis of the fiber push-out and re-push test

Composites Science and Technology, 1998
Abstract The objective of this work is to employ the variational model of a concentric cylinder to model accurately the fiber push-out (and re-push) test used for evaluation of interfacial properties. In this paper, the detailed stress distributions and load/displacement solutions obtained by considering a variety of interface boundary conditions ...

Singularity of Interface Stresses in Fibre Push-Out Test

Key Engineering Materials, 2002
The boundary element method (BEM) is used to analyse the singular behaviour at the free edges of fibre-matrix interface in the fibre push-out test. The fibre push-out test has been widely employed to characterise the interface properties in polymer ...

Analyses of the fiber push-out test

International Journal of Solids and Structures, 1993
Abstract A two-dimensional model of the fiber push-out test is considered. Two distinct methods of analysis are independently employed in solving the problem, and their accuracy is indicated by the virtual coincidence of the results. Interfacial debonding is assumed to be characterized by a cohesive zone model, and subsequent slippage obeys a Coulomb

Push-out test: Why bother?

Journal of Petroleum Science and Engineering, 2019
Abstract Bonding between cement and steel is currently believed to be of key importance in well integrity since it prevents the development of microannulus. Push-out test is often used to quantify the bonding strength between cement and steel in laboratory.

FE validation of push‐out tests

Steel Construction, 2017
AbstractThe prefabrication of concrete slabs reduces construction time and the total life cycle cost of composite steel‐concrete buildings and bridge decks. Using bolts as shear connectors embedded in prefabricated concrete slabs enables reuse and easy replacement of slabs as structural members suitable for a circular economy construction concept.

Simulation of fiber pushing-out test

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2009
The stress distribution on the failure progress of fiber pushed-out test was studied. A numerical program, developed by meso-damage mechanics, was adopted to simulate the whole failure process of interface debonding and fiber pushing out. From the simulation, it can be concluded that, the interfacial stress on load side and support side is larger than ...

Partial-interaction analysis with push-out tests

Journal of Constructional Steel Research, 2005
Abstract This paper deals with an experimental and analytical study to simulate partial-interaction behavior by using push-out results for steel–concrete composite members. In order to analyze the interface behavior of steel–concrete by the degree of interaction, a total of 9 push-out test specimens were tested.

Push-Out Test on Shear Connectors Embedded in UHPC

Applied Mechanics and Materials, 2013
The various push-out tests have been performed to investigate the load carrying capacity and ultimate behavior of headed studs in UHPC (Ultra High Performance Concrete), which has high compressive and tensile strength as well as high durability compared to ordinary concrete.

Interfacial mechanics of push-out tests: theory and experiments

Composites Part A: Applied Science and Manufacturing, 2001
Abstract The thermo-mechanical characterization of interfaces in composite systems (PMC/MMC/IMC/CMC) is one of the challenging problems in composite mechanics and engineering. Each system has its own distinguishing features; however, in MMCs and IMCs the study is rendered more complex due to the evolving chemical species (both temporally and ...

Numerical study of the single fibre push-out test

Composite Interfaces, 1997
The boundary element method (BEM) is used to analyze the stress transfer behaviour in the single fibre push-out test. The result shows that the stress distributions are well compared to those obtained from the shear lag analysis for the majority of the embedded fibre length. The BEM analysis clearly depicts the singular behaviour of interface stresses,
