A blended shifted-fracture/phase-field framework for sharp/diffuse crack modeling
(2023-02-28)
Article
Open AccessThe shifted fracture method (SFM) is an embedded method that enables sharp crack representations while using mesh-fitted data structures. In the SFM, the true crack is embedded in the computational grid, but the crack ... -
A boundary algebraic formulation for plane strain elastodynamic scattering
(Society for Industrial and Applied Mathematics (SIAM), 2018)
Article
Open AccessSolving of elastodynamic problems arises in many scientific fields such as wave propagation in the ground, non-destructive testing, vibration design of buildings, or vibroacoustics in general. An integral formulation based ... -
A combined XFEM phase-field computational model for crack growth without remeshing
(Springer, 2020-10-07)
Article
Open AccessThis paper presents an adaptive strategy for phase-field simulations with transition to fracture. The phase-field equations are solved only in small subdomains around crack tips to determine propagation, while an XFEM ... -
A comparative study on homogenization strategies for multi-scale analysis of materials
(Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2013-02-01)
Book
Open AccessOne of the most important engineering tasks over the years has been the design and manufacture of increasingly sophisticated structural materials as a result of the requirements related to the technological progress. In ... -
A complementary energy approach accommodates scale differences in soft tissues
(2020-05-01)
Article
Open AccessThe mechanics of biological entities, from single molecules to the whole organ, has been extensively analyzed during the last decades. At the smaller scales, statistical mechanics has fostered successful physical models ... -
A computational model for early cell spreading, migration, and competing taxis
(Elsevier, 2023-10)
Article
Open AccessCell motility represents one of the most fundamental functions in life such as organ development or tissue regeneration and diseases such as cancer. Here, we derived a computational model of cell motility that incorporates ... -
A face-centred finite volume approach for coupled transport phenomena and fluid flow
(2024-01-01)
Article
Open AccessWe present a particular derivation of the face-centred finite volume (FCFV) method and study its performance in non-linear, coupled transport problems commonly encountered in geoscientific and geotechnical applications. ... -
A finite element approach to the simulation of hydraulic fractures with lag
(2013)
Article
Open AccessWe presented a finite-element-based algorithm to simulate plane-strain, straight hydraulic fractures in an impermeable elastic medium. The algorithm acCOllllts for the nonlinear coupling between the fluid pressure and the ... -
A four-noded quadrilateral element for composite laminated plates/shell using the refined zigzag theory
(2012-06)
Research report
Open AccessA new bilinear 4-noded quadrilateral element (called QLRZ) for the analysis of composite laminated and sandwich plates/shells based on the refined zigzag theory (RZT) proposed by Tessler et al. [1] is presented. The element ... -

A second-order face-centred finite volume method for elliptic problems
(2020-01-01)
Article
Open AccessA second-order face-centred finite volume method (FCFV) is proposed. Contrary to the more popular cell-centred and vertex-centred finite volume (FV) techniques, the proposed method defines the solution on the faces of the ... -
A simple microstructural viscoelastic model for flowing foams
(2019-03)
Article
Open AccessThe numerical modelling of forming processes involving the flow of foams requires taking into account the different problem scales. Thus, in industrial applications a macroscopic approach is suitable, whereas the macroscopic ... -
A stable XFEM formulation for multi-phase problems enforcing the accuracy of the fluxes through Lagrange multipliers
(2013-11-02)
Article
Open AccessWhen applied to diffusion problems in a multi-phase setup, the popular extended finite element method (XFEM) strategy suffers from an inaccurate representation of the local fluxes in the vicinity of the interface. The XFEM ... -
Adaptive phase-field modeling of fracture in orthotropic composites
(2023-11-15)
Article
Restricted access - publisher's policyAn adaptive phase-field method is developed and applied to model fracture propagation in orthotropic composites. The proposed approach extends the work of Muixí et al. (2020) to orthotropic composites through following ... -
Adaptive phase-field modeling of fracture propagation in bi-layered materials
(2023-11-15)
Article
Restricted access - publisher's policyWe study fracture propagation in bi-layered materials using an adaptive phase-field method. The method combines a phase-field representation of fracture with spatial adaptivity to provide mesh refinement in the smeared ... -
Additioning alfa fibres in cement mortar
(Universidad Católica de Chile (UC), 2018)
Article
Open AccessCement mortar is a broadly used construction material. Adding fibres into the fresh mortar is an effective reinforcing technique to overcome the drawbacks related with the little tensile and flexural strength. Using natural ... -
