本文详细讨论了薄板压缩试验中三个难题的解决方法。目前已达到:能够精确测试金属薄板的最小厚度为0. 085mm;从自动描绘的应力应变δ-ε曲线(即载荷变形的关系曲线)上判读得的弹性模量E和屈服强度δ_(0.2)的误差分别为±2％和±1％;每测一片试件仅八分钟。基本解决了常温下测定薄板压缩性能存在的问题。
This paper discusses in detail how to solve three problems in the sheet compression test. Has now reached: to accurately test the minimum thickness of the metal sheet is 0. 085mm; elastic modulus E and yield strength δ_ (0.2) from the automatic description of the stress-strain δ-ε curve (ie, the relationship between load deformation) The errors were ± 2% and ± 1%, respectively; each test piece only eight minutes. The basic solution to the problem of sheet compression at room temperature.
