Thirty-one materials have been tested in compression in order to generate the stress (force per unit of cross-sectional area) versus strain (deformation) behaviour, for the purpose of assessing the suitability of various foamed plastics and rubbers as shoe insole materials. It was found that the materials could be classified into three distinct categories (very stiff, moderately deformable and very deformable) according to the shape of the characteristic stress versus strain curve. The moderately deformable group has been selected as the most promising for clinical application.
为了评估各种泡沫塑料和橡胶作为鞋垫材料的适用性，对31种材料进行了压缩测试，以得出应力（单位横截面积上的力）与应变（变形）的关系。结果发现，根据特征应力与应变曲线的形状，这些材料可分为三类（非常硬、中等可变形和非常可变形）。中等可变形组被选为最有临床应用前景的组别。
