The stress-strain curve is a graphical measure of the strength and elasticity of a material. It is used to predict the behavior of materials used in a given application. The stress-strain graph provides engineers and designers a graphical measure of the strength and elasticity of a material. ...
此弹性区域的材料模数( 杨氏模数,弹性模数) 为一常数定值;所谓模数Modulus=(stress)/(strain) 即为应力-应变曲线上的对应斜率,在此弹性区域上可以藉由简单的应变量值与起始弹性模数的乘积,来计算出应力值,可作为产品设计上的参考依据。 图2: 塑胶材料的应力- 应变曲线图...

strain curve this is seen as a decrease in the stress. Conversely, if the curve is plotted in terms of true stress and true strain the stress will continue to rise until failure. Eventually the neck becomes unstable and the specimen ruptures (fractures). Most ductile metals other than steel...

Figure 1: A typical stress-strain curve Point A: At origin, there is no initial stress or strain in the test piece. Up to point A Hooke's Law is obeyed according to which stress is directly proportional to strain. That's why the point A is also known as proportional limit. This stra...
