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 ...

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 ...

Coupled fluid-solid thermal interaction modeling for efficient transient simulation of biphasic water-steam energy systems
(Elsevier, 2020-03)
This paper proposes a fluid-solid coupled finite element formulation for the transient simulation of water-steam energy systems with phase change due to boiling and condensation. As it is commonly assumed in the study of ...

Partitioned formulation of contact-impact problems with stabilized contact constraints and reciprocal mass matrices
(John Wiley & Sons, 2021-09)
This work presents an efficient and accuracy-improved time explicit solution methodology for the simulation of contact-impact problems with finite elements. The proposed solution process combines four different existent ...

Energy-conserving interface dynamics with asynchronous direct time integration employing arbitrary time steps
(Elsevier, 2023-08)
The derivation and implementation of an asynchronous direct time integration scheme for domain-decomposed finite element models is presented. To maximize clarity in the description of the proposed asynchronous integration, ...
