Mechanical considerations for polymeric heart valve development: Biomechanics, materials, design and manufacturing
Richard Li,Jonathan B. Russ,Costas Paschalides,Giovanni Ferrari,Haim Waisman,Jeffrey W. Kysar,Jeffrey W. Kysar,David Kalfa +7 more
TL;DR: Of all engineering materials, polymers and polymer-based composites are best able to mimic the tissue-level mechanical behavior of the native leaflet, and these material models have been incorporated into computational models for the optimization of valve geometry, with the goal of minimizing internal stresses and improving durability.

Rupture of 3D-printed hyperelastic composites: Experiments and phase field fracture modeling
TL;DR: In this paper, the authors studied the failure behavior of 3D-printed polymer composites undergoing large deformations and found that the performance of composites can be tuned through selection of the inclusion position.

Topology optimization for brittle fracture resistance
Jonathan B. Russ,Haim Waisman +1 more
TL;DR: In this article, the authors explored the use of the phase field method for fracture in order to increase the fracture resistance, or strength, of a structure prior to failure by directly constraining the phase-field approximation of the fracture surface energy.

A novel elastoplastic topology optimization formulation for enhanced failure resistance via local ductile failure constraints and linear buckling analysis
Jonathan B. Russ,Haim Waisman +1 more
TL;DR: The results demonstrate that structural responses such as peak load carrying capacity and total external work required to reach the peak load may be significantly improved using the suggested framework.

Design optimization of a cardiovascular stent with application to a balloon expandable prosthetic heart valve.
Jonathan B. Russ,Richard Li,Richard Li,Abigail R. Herschman,Abigail R. Herschman,Haim Waisman,Vijay Vedula,Jeffrey W. Kysar,Jeffrey W. Kysar,David Kalfa +9 more
TL;DR: In this paper, a cardiovascular stent design optimization method is proposed with application to a pediatric balloon-expandable prosthetic heart valve, where a stent is situated inside of an expandable polymeric valved conduit.
