inquiry sheet number, a device that can accurately describe the stress-strain curve There is a close relationship between the tensile value and the gauge distance in the tensile sample. For example, the constant extension stress of the sample requires measuring the force value of the sample stretching to the given elongation, while the constant stress requires measuring the gauge distance of the sample stretching to the given stress After the experiment is completed, the accurate stress-strain curve can reproduce the experimental process, and clearly pay attention to the maintenance and protection of the values of each experimental section, so as to facilitate the calculation of the items required by the experiment 161 inquiry time 16:44, December 18, 2019 quotation deadline 23:59, December 21, 2019 inquiry type spot/standard procurement type standard ordering company 1 has always adhered to science and technology as the pilot order (single purchase)
