摘要
研制了基于印压法的软质材料杨氏模量的测量装置,通过有限元仿真方法确定杨氏模量与印压曲线的关系的系数,从而实现对仿组织弹性样本进行杨氏模量量值的标定;用瞬时弹性成像设备对仿组织弹性模体进行测量,其结果与印压法测量结果的一致性,验证了弹性量值传递的可行性。
The measuring equipment of Young＇ modulus of soft materials was developed based on indentation test. Finite element method （FEM） was utilized to determine the coefficients between Young＇ s modulus and indentation profiles. Then the Young＇ s modulus of elastic samples was calibrated by indentation method. Furthermore, the elastic phantoms were measured by commercialized transient elastography equipment. The agreements of measured elastic parameters and the results by indentation method are to verify the feasibility of elastic quantity＇ s transferring.
