Stabilization techniques for immersogeometric analysis of plate and shell problems in explicit dynamics
Giuliano Guarino, Yannis Voet, Pablo Antolin +1
Finite element plate and shell formulations are ubiquitous in structural analysis for modeling all kinds of slender structures, both for static and dynamic analyses. The latter are…
Mass lumping and stabilization for immersogeometric analysis
Yannis Voet, Espen Sande, Annalisa Buffa
Trimmed (multi-patch) geometries are the state-of-the-art technology in computer-aided design for industrial applications such as automobile crashworthiness. In this context, fast…
Mass lumping and outlier removal strategies for complex geometries in isogeometric analysis
Yannis Voet, Espen Sande, Annalisa Buffa
Mass lumping techniques are commonly employed in explicit time integration schemes for problems in structural dynamics and both avoid solving costly linear systems with the consist…
A theoretical analysis of mass scaling techniques
Yannis Voet, Espen Sande, Annalisa Buffa
Mass scaling is widely used in finite element models of structural dynamics for increasing the critical time step of explicit time integration methods. While the field has been flo…
The Immersed Boundary Conformal Method for Kirchhoff-Love and Reissner-Mindlin shells
Giuliano Guarino, Alberto Milazzo, Annalisa Buffa +1
This work utilizes the Immersed Boundary Conformal Method (IBCM) to analyze Kirchhoff-Love and Reissner-Mindlin shell structures within an immersed domain framework. Immersed bound…
An Interior Penalty coupling strategy for Isogeometric non-conformal Kirchhoff-Love shell patches
Giuliano Guarino, Pablo Antolin, Alberto Milazzo +1
This work focuses on the coupling of trimmed shell patches using Isogeometric Analysis, based on higher continuity splines that seamlessly meet the requirement of Kirchhoff-L…
