Second-order structural identification procedure via state-space-based system identification
K. F. Alvin,Kwang-Chun Park +1 more
TL;DR: In this paper, a theory for transforming the system-theory-based realization models into the corresponding physical-coordinate-based structural models is presented, which can be implemented into a computational procedure and applied to several example problems.

Topology optimization for stationary fluid–structure interaction problems using a new monolithic formulation
TL;DR: In this paper, a monolithic procedure employing a unified domain rather than separated domains is proposed for topology optimization in the steady-state fluid-structure interaction (FSI) problem, where the spatial differential operator of the fluid and structural equations for a deformed configuration is transformed into that for an undeformed configuration with the help of the deformation gradient tensor.

A phase-field modeling approach of hydraulic fracture in saturated porous media
Yousef Heider,Bernd Markert +1 more
TL;DR: In this paper, a diffusive phase-field model is used to simulate hydraulic fracture in fluid-saturated heterogeneous materials, which can be implemented in usual continuum finite element packages, allowing for a robust solution of initial-boundary-value problems (IBVP).

Toward patient-specific simulations of cardiac valves: state-of-the-art and future directions.
Emiliano Votta,Trung Le,Marco Stevanella,Laura Fusini,Enrico G. Caiani,Alberto Redaelli,Fotis Sotiropoulos +6 more
TL;DR: It is shown that the significant progress achieved in both fronts paves the way toward clinically relevant computational models that can simulate the performance of a range of heart valves, native and prosthetic, in a patient-specific left heart environment.

Fluid-structure interaction in lower airways of CT-based lung geometries
Wolfgang A. Wall,Timon Rabczuk +1 more
TL;DR: In this article, a partitioned fluid-structure interaction (FSI) approach is employed to study airflow patterns and airway wall stresses in the first generations of lower airways in a real lung geometry.
