Wang & Li 2004 - Tailoring of pre-existing flaws in ECC matrix for saturated strain hardening

Citation

Wang, S., Li, V.C. (2004). Tailoring of pre-existing flaws in ECC matrix for saturated strain hardening. In FraMCoS 2004, Vail, Colorado, pp. 1005–1012.

Atlas role

• Foundational paper for artificial flaw tailoring in ECC.
• Direct support for the idea that pre-existing flaws can be intentionally controlled to promote saturated multiple cracking.
• Directly linked to Victor Li book Chapter 2 references, Ref. 45.

Why it matters

This paper is central to Professor Lee’s low-fiber EGC/EPS bead framing. Victor Li book Chapter 2 explains that artificial flaws with prescribed size distribution can increase the active crack initiator pool and improve tensile strain capacity robustness. This supports describing EPS beads as intentional initial flaws rather than merely weak inclusions.
