CASE STUDY
Fatigue & Hemodynamic Analysis of Aortic Heart Valve
- Fully-coupled fluid-structure analysis using StarCCM & Abaqus
- Fluid dynamically deflects leaflet tissue, imparting physiological loads on stent
- Elasto-plastic, superelastic, & custom anisotropic hyperelastic material models
- Full-field stresses & strains on stent, leaflets, & fluid​
Quartus aids the design process through:
- Manufacturing & fatigue analysis of the stent frame
- Allows for rapid design iterations
- Nitinol, stainless steel, titanium; tube or braid
- Hemodynamic analysis
- Calculation of pressure drop, stagnation, hemolysis, etc.
- Trade studies on geometric & manufacturing parameters
- Regulatory submission analyses
- Verification & validation
- Qualitative & quantitative comparison to in-vitro testing
- Convergence & sensitivity studies
