When modeling any material, the spring can be used to represent an ideal elastic material and the dashpot an ideal viscoelastic material.

当模型的任何材料，弹簧可以用来代表一种理想的弹性材料和粘弹性阻尼器的理想材料。

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。

That 3-D data then got plugged into a solid-modeling program where engineering parameters such as material, thickness and structure were assigned to the shape.
