Representativity of the singular stress state in the failure of adhesively bonded joints between metals and composites
(Elsevier, 2009-09)
Several critical points, where both geometry and material properties change abruptly, arise in an adhesively bonded lap joint between a metallic and a composite material. These critical points, called multimaterial corners ...

Singularity analysis of anisotropic multimaterial corners
(Springer, 2003-01)
Singular stress states induced at the tip of linear elastic multimaterial corners are characterized in terms of the order of stress singularities and angular variation of stresses and displacements. Linear elastic materials ...

A least squares procedure for the evaluation of multiple generalized stress intensity factors at 2D multimaterial corners by BEM
(Elsevier, 2012-03)
Detailed characterization of linear elastic stress states at corners and crack tips requires knowledge of the stress singularity orders, the characteristic angular functions and the generalized stress intensity factors ...

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 ...

Determination of Generalized Fracture Toughness in composite multimaterial closed corners with two singular terms - Part II: Experimental results
(Elsevier, 2012-07)
In this paper the experimental part of the procedure for the Generalized-Fracture-Toughness determination in multimaterial closed corners with two stress singularities is presented. The so-called Generalized-Fracture-Toughness ...
