Vascular dynamic bending significantly affects stent stress and fatigue, and explicit-implicit coupling simulation is a viable method for analyzing these mechanical properties.
Requires incorporation of dynamic bending in stent fatigue testing; leaves open human translation.
The results showed that the effect of VDB has a significant impact on the stent's stress distribution, fatigue performance and overall stress on the vessel, thus it is necessary to be considered when analyzing stent's long-term mechanical properties. Meanwhile, the results showed that the explicit-implicit coupling simulation can be applied to analyze stent mechanical properties.
