Simulation and analysis of single fiber pull-out tests through ANSYS and VC++

Abstract

The aim of this study was to simulate the traditional investigation process of single fiber pull-out tests on quantificational basis, with an estimation of the critical length of embedded fiber and interfacial shear strength while comparing the stimulation results with empirical results. A finite element method (FEM) model of single fiber pull-out tests was established by using ANSYS parametric design language (APDL) program flow. Interfacial average shear strength was calculated and process of interfacial debonding was simulated. Single fiber pull-out tests were implemented to validate the FEM model. Results reveal that the maximum load estimated by the FEM varied as a function of both the length and critical length of the embedded fiber, and the calculated interfacial shear strength through FEM analysis is basically in agreement with the experimental results with a trivial difference of no more than 4.5%. A software was designed to simplify the simulation with respect to the analysis system of single fiber pull-out tests.
