Atherosclerosis is a condition which disrupts blood flow due to plaque build-up inside the arteries. Under conditions where consecutive plaques are prevailing blood hammer principle is exhibited.
The pressure and shear stress produced at an infinitesimal area act as the governing equation for stent modeling. The leading order pressure lays the foundation for the design of cardiac stents with definite dimensions.
The designed stent was encapsulated inside a crimper validated through ANSYS-static and transient structural simulation to derive the total deformation, equivalent strain, and stress exerted on the stent. Five different biomaterials stainless steel 316, cobalt, chromium, platinum, and Poly lactic acid were selected for the material assessment.
Static and Transient structural analysis for a period of 1 and 10 secs was implemented for a stent with and without a crimper. The material performance in terms of total deformation, equivalent stress, and strain are analyzed.
The paper envisions the dynamics of blood hammer in atherosclerosis that provides the changes in the pressure and clotting process. It shows the promising results of the stent behavior in varied forces which gives valuable insights for future improvement in stent design and material selection.
动脉粥样硬化是一种由于动脉内部斑块积聚而导致血流中断的疾病。在连续斑块占主导地位的情况下，会出现血液锤击原理。
在微小面积上产生的压力和剪切应力是支架建模的控制方程。主导压力为具有确定尺寸的心脏支架设计奠定了基础。
设计的支架被封装在一个验证通过 ANSYS 静态和瞬态结构模拟的压接器中，以得出支架上的总变形、等效应变和所施加的应力。选择了五种不同的生物材料不锈钢 316、钴、铬、铂和聚乳酸来进行材料评估。
对带有和不带有压接器的支架进行了 1 秒和 10 秒的静态和瞬态结构分析。分析了材料在总变形、等效应力和应变方面的性能。
本文预见了动脉粥样硬化中血液锤击的动力学，提供了压力和凝血过程的变化。它展示了支架在不同力下的良好行为，为未来改进支架设计和材料选择提供了有价值的见解。
