The current FE modeling strategy is insufficient, however, and significant modifications must be made to better mimic whole bone elastic and inelastic material behavior.

然而，现有的FE模型是不足的，必须作有效的修正来更好地模拟整个骨的弹性及非弹性材料特性。

Furthermore the research on the FEM modeling of strain softening material is reviewed followed by the introduction of a FEM modeling based on the displacement-controlled method.

此外，介绍了关于应变软化材料有限元数值模拟的一些研究进展，并且介绍了适合应变软化材料有限元数值模拟的位移控制法。
