To find this point, a line is drawn parallel to the elastic region of the curve (slope = E), intersecting the x-axis at a strain of 0.002 (0.2%). This line intersects the stress-strain curve at the yield point. The stress at this point is Y. 1.4.3 Tensile Strength The tensile ...

40 硬度 eva 压缩反力 stress strain curve 材料的压缩反力与应力-应变曲线(stress-strain curve)之间的关 系取决于材料的硬度、弹性模量等性质。EVA(乙烯-醋酸乙烯共聚物) 通常是一种弹性较好的材料,其应力-应变曲线可能表现为一个典型 的弹性区域,然后是一个流变区域。 在理想的弹性区域,应力(stress)与应变(...
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...

ber reinforced concrete for compression, the stress±strain behavior of the material in compression is needed. While the compressive strength is used for the strength calculation of the structural components, the stress±strain curve is needed to evaluate the toughness of the material for consideration...
