摘　　要：通过对受压铸铁试件受力和斜截面应力的分析,得出铸铁在摩擦力和轴心压力共同作用下,其破坏面与横截面的夹角为45°+φ/2(φ为铸铁与试验机压头间的摩擦角)。After the analysis of bearing force of the compressed cast iron and stress of its slanting section, it is derived that because of the function of the friction force and axial stress, the angle between the failure plane and the cross section is 45°＋φ/2 （φ is the friction angle between cast iron and the pressure head of testing machine）.

关 键 词：摩擦力 摩擦角 破坏面 最大剪应力
