塑性变形临界点检测

检测项目

上屈服强度检测：测定材料在屈服期间首次下降前的最高应力值，表征材料抵抗初始塑性变形的能力。

下屈服强度检测：当屈服呈现平台现象时，测定不计初始瞬时效应期间的最低应力值。

规定塑性延伸强度检测：测定规定塑性延伸率对应的应力，常用于无明显屈服点的金属材料。

规定总延伸强度检测：测定规定总延伸率对应的应力，总延伸包含弹性与塑性两部分。

抗拉强度检测：测定试样在断裂前所能承受的最大名义应力，是材料强度的极限指标。

弹性模量测定：在弹性变形阶段内，应力与应变的比值，反映材料的刚性。

泊松比测定：测定材料在弹性范围内横向应变与轴向应变的绝对值之比。

应变硬化指数测定：表征材料在塑性变形阶段抵抗继续变形的能力变化规律。
