Artificial models can be useful at approximate and qualitative research, which should give the preliminary results. Artificial models are usually made of photo-elastic plastic e.g.. juvidur, araldite in the three-dimensional contour shape of the bone. Anatomical preparations consist of the same heterogeneous, structural materials with extremely anisotropic and unequal highly elastic characteristics, which are embedded in a complex organic structure.
Examine the budget voltage and deformation of: on the compressive and bending forces on juvidur and veal bone models and compared the results of these two methods (juvidur, veal bone).
For the experimental study were used geometrically identical, anatomically shaped models of Juvidur and veal bones diameter of 30 mm and a length of 100 mm. Static tests were performed with SHIMADZU AGS-X testing machine, where the force of pressure (compression) increased from 0 N to 500 N, and then conducted relief. Bending forces grew from 0 N to 250 N, after which came into sharp relief.
On models of juvidur and veal bones studies have confirmed that uniform stability at the site of the fracture MIF with a coefficient ranking K=0,1971, K=0,2704, K=0,2727 i K=0,5821.
On models of juvidur and veal bones working with Shimadzu AGS-X testing machine is best demonstrated MIF with a coefficient of 0.1971.
人工模型在近似和定性研究中可能有用，这类研究应给出初步结果。人工模型通常由光弹性塑料制成，例如，用聚脂树脂、合成树脂制成骨骼的三维轮廓形状。解剖标本由相同的异质结构材料组成，具有极各向异性和不等的高弹性特征，这些材料嵌入复杂的有机结构中。
研究聚脂树脂和小牛肉骨模型在压缩力和弯曲力作用下的预算电压和变形，并比较这两种方法（聚脂树脂、小牛肉骨）的结果。
实验研究使用了几何形状相同、解剖形状的聚脂树脂和小牛肉骨模型，直径30毫米，长度100毫米。使用岛津AGS-X试验机进行静态测试，压力（压缩）力从0牛增加到500牛，然后进行释放。弯曲力从0牛增加到250牛，之后急剧释放。
在聚脂树脂和小牛肉骨模型上的研究证实，骨折部位MIF处的均匀稳定性系数分别为K = 0.1971、K = 0.2704、K = 0.2727和K = 0.5821。
使用岛津AGS-X试验机对聚脂树脂和小牛肉骨模型进行研究，最能证明系数为0.1971的MIF。
