き裂先端変位の英語

ここで、ＣＴＯＤはｍｍ単位での亀裂先端開口変位、Δａはｍｍ単位での延性亀裂成長長さ、Ｃは係数、ｎは指数を表す。例文帳に追加

In the formula, the CTOD and Δa respectively denote the crack tip opening displacement (mm) and the grown length of a ductile crack (mm) and C and n respectively denote a coefficient and an index. - 特許庁

き裂伝播が大きい領域での飽和き裂先端開口変位（δＲ−ｐｌａｔｅａｕ）が１mm以上で、かつ該領域でのＹＲが９０％以下、一様伸びが３〜１０％であることを特徴とする高速延性破壊特性に優れた超高強度鋼管。例文帳に追加

In the superhigh strength steel pipe having high speed ductile fracture characteristics, the saturation crack tip opening displacement (δR- plateau) in a region having high crack propagation is ≥1 mm, also YR(yield ratio) in the above region is ≤90%, and uniform elongation is 3 to 10%. - 特許庁
