A novel procedure to determine the cohesive law In DCB tests
(Elsevier, 2017-11-10)
A novel method is presented for the determination of mode I cohesive law for the characterization of delamination in unidirectional carbon fiber reinforced polymer laminates. The energy release rate as a function of the ...
A New Approach For Determining The R-Curve In DCB Tests Without Optical Measurements
(Elsevier, 2015-02)
A new method for obtaining the R-curve point to point by the Double Cantilever Beam test is proposed. Besides the determination of new compliance and energy release rate equations, the analytical model presented leads to ...
Analysis of a reversible five-point bending configuration based on a novel two-sense support
(Elsevier, 2015-05)
A novel two-sense support for flexural tests has been designed and manufactured in Ikerlan. The aim of this support is to do two-sense bending fatigue tests. In order to reduce the displacement corresponding to a given ...
Analytical and numerical approach of an End Notched Flexure test configuration with an inserted roller for promoting mixed mode I/II
(Elsevier, 2015-06-22)
A test configuration for studying mixed-mode is analyzed analytically and numerically. It is based on the End Notched Flexure test, inserting a roller in the cracked part in order to promote mixed mode I/II. The analytical ...
Numerical assessment of an experimental procedure applied to DCB tests
(Elsevier, 2020-02)
Numerical analysis of the analytic model of an experimental procedure to determine the crack length, the compliance and the energy release rate has been developed. As a first step, bending tests at different spans have ...
Experimental assessment of an End Notched Flexure test configuration with an inserted roller for analyzing mixed-mode I/II fracture toughness
