Experimental Analysis of Interfacial Debonding on Resin/Fiber by Pinhole-Type Pull-Out Test

Analysis of Bond Strength by Pull Out Test on Fiber Glass Posts Cemented in Different Lengths

BACKGROUND The aim of this study was to evaluate, by means of pull-out test, the bond strength of fiberglass posts when cemented with different lengths in endodontically treated teeth. MATERIALS AND METHODS Sixty single-rooted bovine roots were cut in the cementoenamel junction with 21 mm length. They were endodontically treated and randomly divided into three groups (n = 20). Group 1 - Prepa...

1 Interfacial Characterization by Pull - Out Test of 2 Bamboo Fibers Embedded in Poly ( lactic acid ) 3

In this work, the apparent shear strength at the interface between a bamboo fiber and the 26 surrounding poly(lactic acid) (PLA) matrix is quantified. A method for processing pull-out test 27 samples within a controlled embedded length is proposed and the details of the test procedure are 28 presented, along with a critical discussion of the results. Two series of samples are considered: 29 unt...

Theoretical and Experimental Investigation into the Adhesion between Fiber-Reinforced Bitumen and Aggregates by Using Pull-out Method

Maximum pull out force on DNA hybrids

We discuss theoretically the force F between two colloidal particles, each of them carrying one single strand DNA. The two strands are complementary only on a finite sequence of (`) consecutive base pairs. We define an adjustment length κ−1 (a few base pairs): in the adjustment regions near both ends of the paired region, the tension is still mainly on one single strand. But in the central part...

Micromechanics-Based Interfacial Debonding Model of Functionally Graded Materials

This study develops a micromechanical damage model for two-phase functionally graded materials considering the interfacial debonding of particles and pair-wise interactions between particles. Given an applied mechanical loading, in the particle-matrix zones, the interactions from all other particles over the representative volume element are integrated to calculate the homogenized elastic field...
