Autor: Jonathan B. Russ, Richard L. Li, Abigail R. Herschman, Haim Waisman, Vijay Vedula, Jeffrey W. Kysar, David Kalfa
Publikováno v: Materials & Design, Vol 209, Iss , Pp 109977- (2021)
A cardiovascular stent design optimization method is proposed with application to a pediatric balloon-expandable prosthetic heart valve. The prosthetic valved conduit may be expanded to a larger permanent diameter in vivo via subsequent transcatheter

Probabilistic Model Updating for Sizing of Hole-Edge Crack Using Fiber Bragg Grating Sensors and the High-Order Extended Finite Element Method
Autor: Jingjing He, Jinsong Yang, Yongxiang Wang, Haim Waisman, Weifang Zhang
Publikováno v: Sensors, Vol 16, Iss 11, p 1956 (2016)
This paper presents a novel framework for probabilistic crack size quantification using fiber Bragg grating (FBG) sensors. The key idea is to use a high-order extended finite element method (XFEM) together with a transfer (T)-matrix method to analyze

AN ANISOTROPIC EXTENSION FOR A THERMOVISCOPLASTIC GTN DUCTILE DAMAGE MODEL
Autor: João Paulo Pascon, Haim Waisman
Publikováno v: International Journal for Multiscale Computational Engineering. 21:1-24
In this work, a thermoviscoplastic GTN ductile damage model is extended to account for anisotropic plastic behavior. The novel feature of the proposed model is the enrichment of a GTN model, with the Hill's yield criterion accounting for hardening, s

Level-Set Topology Optimization for Ductile and Brittle Fracture Resistance Using the Phase-Field Method
Autor: Nima Noii, Hassan Ali Jahangiry, Haim Waisman
This work presents a rigorous mathematical formulation for topology optimization of a macrostructure undergoing ductile failure. The prediction of ductile solid materials which exhibit dominant plastic deformation is an intriguingly challenging task
