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 ...

A finite element implementation of phase-field approach of fracture for nonlinear solid shells including inelastic material behavior
(ELSEVIER, 2024)
The parametrization of shell structures using the so-called solid shell concept has been widely exploited in the last decades. This trend is mainly attributed to the relatively simple kinematic treatment of solid shells ...

Static and fatigue performance of non-circular rivet joints: Comparison between numerical modelling and preliminary testing
(Elsevier, 2024)
Alternative non-circular rivet joint geometries are investigated. An optimum non-circular rivet geometry based on a continuous change in the radius of curvature is proposed to minimise the stress concentration factor ...
