A finite element implementation of phase-field approach of fracture for nonlinear solid shells including inelastic material behavior
(Elsevier, 2024-06)
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 ...

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 ...

A new crack-tip element for the logarithmic stress-singularity of Mode-III cracks in spring interfaces
(Springer, 2024-02)
A new crack-tip finite element able to improve the accuracy of Finite Element Method (FEM) solutions for cracks growing along the Winkler-type spring interfaces between linear elastic adherents is proposed. The spring model ...

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 ...

Fatigue crack initiation and damage characterization in Brazilian test specimens for adhesive joints
(Taylor & Francis, 2014)
The present study is focused on the fatigue failure initiation at bimaterial corners by means of a configuration based on the Brazilian disc specimens. These specimens were previously used for the generalized fracture ...
