Failure initiation criterion in bonded joints with composites based on singularity parameters and practical procedure for design purposes
(Tailor & Francis, 2015)
Composite to metal adhesively bonded joints generates critical points where geometry and material properties change abruptly. These points (multimaterial corners) are potential locations for failure initiation. There exist ...

A modified Brazilian test for the generalized-fracturetoughness determination in multimaterial corners. Numerical and experimental results
(AEMAC (Asociación Española de Materiales Compuestos), 2011)
In the present work, a general procedure for the experimental evaluation of the generalized fracture toughness in multimaterial corners is defined. The proposed method is suitable for closed corners (all material wedges ...

Tensile and shear strength of bimaterial interfaces within composite materials
(Elsevier, 2016-03)
The determination of the tensile and shear strengths of homogeneous materials can be easily performed by standard tensile and shear (e.g. Iosipescu) tests. Nevertheless, when the determination of these strengths involves ...

Determination of Generalized Fracture Toughness in composite multimaterial closed corners with two singular terms - Part I: Test proposal and numerical analysis
(Elsevier, 2012-07)
In the present work a general procedure for the experimental evaluation of Generalized-Fracture-Toughness values at multimaterial closed corners is defined. The lack of symmetries in the stress fields at multimaterial ...

Representativity of thermal stresses in designing composite joints based on singular stress states at multimaterial corners
(Elsevier, 2011-09)
Using adhesives curing at temperature in bonded joints between dissimilar materials (composites and metals) gives rise to residual stresses due to the difference in the value of the thermal expansion coefficients of the ...
