Effect of thermal residual stresses on matrix failure under transverse tension at micromechanical level: A numerical and experimental analysis
(Elsevier, 2011)
In the present work the influence at micromechanical scale of thermal residual stresses, originated in the cooling down associated to the curing process of fibrous composites, on inter-fibre failure under transverse tension ...

Experimental study of the size effect on transverse cracking in cross-ply laminates and comparison with the main theoretical models
(Elsevier, 2019-01)
Transverse cracking of off-axis plies is typically the first step of some failure mechanisms in long fiber reinforced laminated composites. It is well known that the off-axis ply thickness affects strongly the strain level ...

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 ...

A critical study on the experimental determination of stiffness and viscosity of the human triceps surae by free vibration methods
(Sage, 2013-09)
Muscles and tendons play an important role in human performance. Their mechanical behaviour can be described by analytical/numerical models including springs and dampers. Free vibration techniques are a widely used approach ...

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 ...
