灰铸铁抗拉强度与抗剪强度的关系

Relationship Between Tensile Strength and Shearing Strength of Gray Cast Iron

对灰铸铁的抗拉强度和抗剪强度进行测量,将试验数据进行拟合回归得出抗拉强度与抗剪强度的关系曲线。找出了单铸试棒和本体试棒抗拉强度及抗剪强度之间的差别。

Tensile and shear strength of gray iron were tested. Regressive analysis of the test data was conducted. As the result,a tensile strength-shear strength relationship curve was obtained,and the tensile and shear strengths differences between separated test bars and attached test bars were found out.
