Researchers at the University of Ottawa develop experimental and computational methods to improve biomechanical models of heart valves for cardiovascular surgery planning.
In this interview, Prof. Michel Labrosse and Dr. Reza discuss how biaxial mechanical testing is used to determine material properties of cardiac tissues and validate hyperelastic constitutive models. Using controlled biaxial loading, multiple specimen attachment methods, and image-based strain analysis, experimental data are integrated into finite element simulations to compare testing configurations and improve model accuracy.
This work highlights the critical role of validated experimental data in advancing predictive simulations for cardiovascular biomechanics and surgical applications.
