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 ...

Notched-butt test for the determination of adhesion strength at bimaterial interfaces
(Taylor & Francis / Koninklijke Brill NV, 2011)
For the experimental determination of adhesion strength between materials it is desirable to have a uniform stress distribution within the interface of the specimen. The common butt-test with a flat interface between two ...

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 ...
