Discontinuous quarter-point boundary elements revisited: Computation of T-stress in two-dimensional cracked components
(Elsevier, 2023-12)
This paper analyzes the use of discontinuous quarter-point quadratic elements in a dual or hypersingular boundary element context to compute the T-stress for cracked 2-D isotropic components. The performance of this ...

A common framework for the robust design of tuned mass damper techniques to mitigate pedestrian-induced vibrations in lively footbridges
(Elsevier Ltd, 2021)
The dynamic response of modern slender footbridges is usually sensitive to both the pedestrian actions and the uncertainties associated with their inherent structural behavior. Thus, tuned mass dampers have been widely ...

Accurate determination of the stiffness properties for an elastic interface under peeling conditions between homogeneous materials
(Elsevier, 2022-04)
In this paper, several models for analysing peeling tests are considered, including numerical models based on FEM, semi-analytical approaches, and beam models including an elastic interface. Results show that none of the ...

Tensile and shear strength of bimaterial interfaces within composite materials
(Elsevier, 2016-03)
The determination of the tensile and shear strengths of homogeneous materials can be easily performed by standard tensile and shear (e.g. Iosipescu) tests. Nevertheless, when the determination of these strengths involves ...
