three dimensional effective stressとは 意味・読み方・使い方

Before mean effective stress exceeds a phase transformation line, the degree of cumulative damage is sequentially computed on the basis of stress equivalent to the amount of increase from an unloading point in a three-dimensional stress space (steps 208-218).例文帳に追加
