Bi-penalty stabilized technique with predictor–corrector time scheme for contact-impact problems of elastic bars
(Elsevier, 2021-11)
This paper presents a stabilization technique for the finite element modelling of contact-impact problems of elastic bars via a bi-penalty method for enforcing contact constraints while employing an explicit predictor–corrector ...

Inverse mass matrix for isogeometric explicit transient analysis via the method of localized Lagrange multipliers
(John Wiley & Sons, 2019-03)
A variational framework is employed to generate inverse mass matrices for isogeometric analysis (IGA). As different dual bases impact not only accuracy but also computational overhead, several dual bases are extensively ...

Tratamiento de elementos rectos y curvos de sección variable por métodos matriciales
(Scipedia, 1989)
En este trabajo se presenta la formulación necesaria para el tratamiento de elementos de directriz recta o circunferencial con características geométricas e inerciales variables según la directriz, así como de las cargas ...

Estudio numérico de la propagación de ondas elásticas en placas y de su interacción con defectos
(2003)
Las ondas elásticas guiadas en elementos estructurales (tuberías, placas, etc.), están siendo utilizadas en la actualidad para desarrollar técnicas de ensayo, no destructivo de largo alcance como alternativa rápida y ...

Inverse mass matrix via the method of localized lagrange multipliers
(National Technical University of Athens, 2017-06)
An efficient method for generating the mass matrix inverse is presented, which can be tailored to improve the accuracy of target frequency ranges and/or wave contents. The present method bypasses the use of biorthogonal ...

Three-field partitioned analysis of fluid–structure interaction problems with a consistent interface model
(Elsevier, 2023)
This paper proposes a new Fluid–Structure Interaction computational framework. The coupling between the solid and an incompressible fluid is formulated by means of the method of localized Lagrange multipliers (LLM). Instead ...

Thermal Modeling of the Port on a Refining Furnace to Prevent Copper Infiltration and Slag Accretion
(MDPI, 2021-11)
Fire refining of blister copper is a singular process at very high temperatures (~1400 K), which means the furnace is exposed to heavy thermal loads. The charge is directly heated by an internal burner. The impurities in ...
