补充资料:压缩试验
测定材料在轴向静压力作用下的力学性能的试验,是材料机械性能试验的基本方法之一。试样破坏时的最大压缩载荷除以试样的横截面积,称为压缩强度极限或抗压强度。压缩试验主要适用于脆性材料,如铸铁、轴承合金和建筑材料等。对于塑性材料,无法测出压缩强度极限,但可以测量出弹性模量、比例极限和屈服强度等。与拉伸试验相似,通过压缩试验可以作出压缩曲线。图中为灰铸铁和退火钢的压缩曲线。曲线中纵坐标P为压缩载荷,横坐标Δh为试样承受载荷时的压缩量。如将两坐标值分别除以试样的原截面积和原高度,即可转换成压缩时的应力-应变曲线。图中Pp为比例极限载荷,P0.2为条件屈服极限载荷,P b为破坏载荷。在压缩试验中,试样端面存在较大的摩擦力,影响试验结果。试样越短影响越大,为减少摩擦力的影响,一般规定试样的长度与直径的比为1~3,同时降低试样的表面粗糙度,涂以润滑油脂或垫上一层薄的聚四氟乙烯等材料。
