During no portion of this curve is the stress(应力) proportional to the strain(应变).
举一反三
- 下列关于“应力、应变”的说法不正确的是 ( )。 A: 应力(stress)定义为“分布内力在一点的集度[ Pa]”,分:正应力σ和切(剪)应力τ; B: 应变(strain)定义为“单位长度的线变形量[m/m(无量纲)]”,分:正应变ε和切(剪)应变γ; C: 正应变(normal strain)ε和切应变(shearing strain)γ分别是由正应力σ和切应力τ所产生的; D: “应力-应变关系曲线”—“物性曲线”一般是线性的,即:应力与应变成正比;
