试样不同横截面积测定方法对抗拉强度测试结果的影响

Effect of inspecting way at different cross-sectional area on inspection result of tensile strength

以3003-H24铝合金冷轧板50 mm定标距的矩形试样为研究对象,通过选取试样不同的位置和点数,测定试样的原始横截面积,计算出板材的抗拉强度,验证试样不同原始横截面积测定方法对抗拉强度测试结果的影响。

The rectangular inspection sample of cold rolled 3003-H24 aluminium sheet has been inspected with space scales of 50mm. The original area of cross section has been inspected with different selecting of inspection position and points. The tensile strength of the aluminum sheet has been estimated by calculation. Using the calculated tensile strength to veify the effect of different inspection way at the original cross section area on the testing result of tensile strength.
