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 ...

Investigating correlations between translucency and wear resistance in lithium silicate-based dental glass-ceramics
(Elsevier, 2024)
Lithium silicate-based glass-ceramics are widely employed dental materials, showing superior aesthetics (determined by translucency) but poorer wear resistance under severe contact conditions than alternative, artificial ...

Closed-form expressions for computing flexoelectric coefficients in textured polycrystalline dielectrics
(Elsevier, 2024-01)
The volume average of the constituting properties of a textured polycrystalline aggregate (the Voigt average) provides a simple way to estimate the effective properties of such an aggregate in terms of its crystallographic ...

Closed-form methodology for the structural analysis of stiffened composite plates with cutouts and non-uniform lay-up
(Elsevier, 2024-09-01)
Building upon the methodology developed in prior studies, which utilized the Lekhnitskii formalism to address composite plates featuring cutouts, varying thicknesses, and different stacking sequences, the present work ...

Robust improvement of the finite-element-model updating of historical constructions via a new combinative computational algorithm
(Elsevier, 2024-04)
Finite-element-models are usually employed to simulate the behaviour of historical constructions. However, despite the high complexity of these numerical models, there are always discrepancies between the actual behaviour ...

Computational modelling of hydrogen assisted fracture in polycrystalline materials
(Elsevier, 2022-09-01)
We present a combined phase field and cohesive zone formulation for hydrogen embrittlement that resolves the polycrystalline microstructure of metals. Unlike previous studies, our deformation-diffusion-fracture modelling ...
