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 DCB test of angle-ply laminates including bending-twisting coupling
(Elsevier, 2018-02-13)
Se analiza la fractura interlaminar de laminados simétricos y antisimétricos angulares mediante el método Double Cantilever Beam. Como los semi-laminados son simétricos en ambos casos, se produce un acoplamiento de ...

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 ...
Application of the dual integrated force method to the analysis of the off-axis three-point flexure test of unidirectional composites
(SAGE Journals, 2015-03-13)
This paper shows the use of the dual integrated force method in the finite element method and its application to unidirectional composite laminates. This method was developed by SN Patnaik for isotropic materials, considering ...
Comparison between the stiffness method and the hybrid method applied to a circular ring
(Springer, 2018-01-17)
This study deals with the comparison of stresses and displacements of a circular ring obtained by two numerical formulations, namely the stiffness method and the hybrid method, applied to isoparametric quadrilateral elements. ...
Experimental assessment of an End Notched Flexure test configuration with an inserted roller for analyzing mixed-mode I/II fracture toughness
(Elsevier, 2016-09)
This study describes the experimental work related to a test configuration proposed recently, based on an End Notched Flexure test configuration modified with an inserted roller. Various mixed-mode ratio tests have been ...
