铸铁压缩破坏的应力分析

An Analysis of Destructive Stress in Iron-casting Contraction

用不同长径比的灰口铸铁圆柱试样和氯氧镁混合物试样进行压缩试验 ,研究其端面摩擦力对试件破坏断口的影响 。

Contracting trial has been carried out with the sylinder testpiece of grey cast iron of different slenderness ratio and the testpiece of the mixture of Cl,O and Mg.The effect on the face frictional force agginst the destruction to the fracture of the testpiece is studied.The state of stress and the cause of destruction are analysed.
