Abstract
Description
式中、σ0は、開口δ0に対応する最大架橋応力であり、Kmは、マトリックス破壊じん性であり、Emは、マトリックスのヤング率である。
σcs<σ0 (3)
式中、σcsは、マトリックス破壊じん性Km及び前から存在する内部欠陥の大きさa0によって求められる。エネルギー判定基準(式1)が、クラック伝播モードを支配するが、式3が表す強度に基づく判定基準が、クラックの開始を制御する。式1と3の双方を満足することが、工学的セメント系複合材挙動を実現するのに必要であり;そうでないと、普通の引張軟化繊維強化挙動がもたらされる。これらのマイクロ工学的解析の詳細は、これまでの研究から知ることができる。
