Analytical Fracture Mechanics Analysis of the Pull-out Test including the Effects of Friction and Thermal Stresses
The energy release rate for propagation of a debond in a single-fiber pull out test was derived analytically. The key finding was that an accurate analysis can be derived by a global energy analysis that includes effects of residual stresses and interfacial friction but does not need to include the details of the stress state at the interfacial crack tip. By comparison to finite elements analys...
متن کامل1 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...
متن کاملFracture Mechanics Analysis of the Single-Fiber Pull-Out Test and the Microbond Test Including The Effects of Friction and Thermal Stresses
The energy release rate for propagation of a debond in either a single-fiber pull-out test or a microbond test was derived analytically. The key finding was that an accurate analysis can be derived by a global energy analysis that includes effects of residual stresses and interfacial friction but does not need to include the details of the stress state at the interfacial crack tip. The analytic...
متن کاملAnalysis 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...
متن کاملSliding friction on wet and dry sand.
We show experimentally that the sliding friction on sand is greatly reduced by the addition of some-but not too much-water. The formation of capillary water bridges increases the shear modulus of the sand, which facilitates the sliding. Too much water, on the other hand, makes the capillary bridges coalesce, resulting in a decrease of the modulus; in this case, we observe that the friction coef...
