一引言单轴拉伸试验是金属材料最广泛采用的一种力学性能试验方法。通过试验。可以得到有关材料弹性、塑性、强度等一整套拉伸性能数据。其中真应力-应变曲线,反映了材料所经历的应力-应变关系,已成为深 An introduction to uniaxial tensile test is the most widely used mechanical properties of a test method. Through the test. You can get the material elasticity, plasticity, strength and a set of tensile properties of the data. The true stress-strain curve, which reflects the stress-strain relationship experienced by the material, has become deep
