sunyinlin(sunyinlin) 发表:AC7101标准中规定:If the specification does not reference a specific strain rate, the strain rate for both room and elevated temperature tensile testing is to be 0.003 to 0.007 inch/inch/minute through yield, and 0.05 inch/inch/minute after yield, with the yield point being determined at 0.2% offset, unless specified otherwise.
拉伸试验中应力应变速率屈服前为0.003到0.007 in/in/min,屈服后的速率为0.05in/in/min.
而新三思给我们设定的移动速率为2mm/min,这是如何转换的?是否符合以上规范要求?国产设备可以实现应力应变速率控制吗?
