The flexure modulus of elasticity of standard stainless steel orthodontic wires was determined by the use of an iterative finite element technique to be 25.4 x 10(6) psi (175 x 10(3) MN/m2). This technique accounts for the configurational changes in the test specimens due to the relatively large deflection during the cantilever test. Under these conditions, the elementary strength of materials relationships does not accurately describe the flexure characteristics of the wires.
通过使用迭代有限元技术测定，标准不锈钢正畸丝的挠曲弹性模量为25.4×10⁶磅力/平方英寸（175×10³兆牛顿/平方米）。该技术考虑了在悬臂测试期间由于相对较大的挠度而导致的测试样本的构型变化。在这些条件下，材料力学的基本关系不能准确描述钢丝的挠曲特性。
