Isogeometric Analysis: Some recent advances with applications to complex and coupled problems

Alessandro Reali, University of Pavia

Abstract

Isogeometric Analysis (IGA) is a successful simulation framework originally proposed by T.J.R. Hughes et al. in 2005, with the aim of bridging Computational Mechanics and Computer Aided Design. In addition to this, thanks to the high-regularity properties of its basis functions, IGA has shown a better accuracy per degree-of-freedom and an enhanced robustness with respect to standard finite elements in many applications, ranging from solids and structures to fluids, as well as to different kinds of coupled problems, also opening the door to the approximation in primal form of higher-order partial differential equations.
After a concise introduction of the basic isogeometric concepts, this lecture aims at presenting an overview of some recent advances with a special focus on coupled problems where the characteristics of IGA seem to be of great advantage, including the simulation of fluid-structure interaction in different contexts (e.g., biomedical problems), studies on the effects of mechanically-induced stresses on prostate cancer growth, thermo-mechanical simulations for additive manufacturing processes, electro-mechanical simulations for biological tissues, and the use of phase-field modeling for fracture and topology optimization problems or for predicting the polarization evolution in elastic ferroelectric materials.
