A phase-field fracture model for fatigue using locking-free solid shell finite elements: Analysis for homogeneous materials and layered composites
(Elsevier, 2023-10)
A computational framework to model fatigue fracture in structures based on the phase-field method and the solid-shell concept is herein presented. With the aim of achieving a locking free solid-shell finite element formulation ...

Revisiting the problem of a crack impinging on an interface: A modeling framework for the interaction between the phase field approach for brittle fracture and the interface cohesive zone model
(Elsevier, 2017-07)
The problem of a crack impinging on an interface has been thoroughly investigated in the last three decades due to its important role in the mechanics and physics of solids. In the current investigation, this problem is ...

A multifield coupled thermo-chemo-mechanical theory for the reaction-diffusion modeling in photovoltaics
(Wiley, 2023-03)
A comprehensive coupled thermo-chemo-mechanical modeling framework is proposed in this work to study the reaction-diffusion phenomena taking place inside photovoltaics (PV). When exposed to hygrothermal conditions, ...
Article
A continuum large-deformation theory for the coupled modeling of polymer–solvent system with application to PV recycling
(Elsevier, 2023-06)
Nowadays recycling of photovoltaics (PV) using the solvent method is becoming a very hot topic as massive products deployed in the last century have approached the end of their service lifetime. The key problem in the ...

Fracture of solar-grade anisotropic polycrystalline Silicon: A combined phase field–cohesive zone model approach
(Elsevier, 2018-03)
This work presents a novel computational framework to simulate fracture events in brittle anisotropic polycrystalline materials at the microscopical level, with application to solar-grade polycrystalline Silicon. Quasi-static ...

Hygro-thermo-mechanical modeling of thin-walled photovoltaic laminates with polymeric interfaces
(Elsevier, 2022-12)
A three-dimensional hygro-thermo-mechanical computational framework for photovoltaic (PV) laminates as well as its numerical implementation are established in this work. Aiming at an efficient thermo-mechanical modeling ...
Article
A framework for the analysis of fully coupled normal and tangential contact problems with complex interfaces
(Elsevier B.V., 2021)
An extension to the interface finite element with eMbedded Profile for Joint Roughness (MPJR interface finite element) is herein proposed for solving the frictional contact problem between a rigid indenter of any ...
