It demonstrated that the experiment of hardness is likely to upset in the experiment of compression. Hardness tester indenter make matrix metal plastic deformation and viscous flow happen. 结果表明,硬度实验类似于压缩实验中的镦粗,硬度计压头可使金属基体发生塑性变形及粘性流动。
And the temperature in the core of rubber test piece under dynamic condition was measured with improved Goodrich compression fatigue tester. 使用经改造的压缩疲劳试验机测试了橡胶试样在动态下的心部温度。
