摘要
从自治基本原理出发,引入本征应变、割线模量、弹性对比材料等概念,结合平均场理论方法,提出了普适性双相合金材料的自洽框架,并进而将其用于预告钨合金材料在单轴拉伸条件下的本构行为。对93wt%钨合金所得到的单轴拉伸实验曲线证实,本理论框架具有今人满意的精度和可靠性。
An universal self-conistent constitutive frame for dual-phase alloys was proceed based on the principle of self-consistency theory and making use of concepts on secant modulus,inherent strain,elastic comparison material,and the uniform field theory etc.This frame is used to predict the constitutive behavior of tungsten alloys under uniaxial tension.The experimental results show that the above constitutive frame gives very satisfactory precision and reliability.
