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 ...

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 ...

Prediction of welding residual stresses and displacements by simplified models. Experimental validation
(Elsevier, 2010-03)
Numerical simulations of welding processes are complex and computationally expensive. Several simplificative hypotheses are typically used in the simulations for time saving considerations, some of which have been explored ...

Evaluation of the stiffnesses of the Achilles tendon and soleus from the apparent stiffness of the triceps surae
(SAGE, 2015-01)
The triceps surae plays an important role in the performance of many sports. Although the apparent average mechanical properties of the triceps surae may be a satisfactory parameter for estimating the training level of an ...

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 ...
