On DIC measurements of DeltaKeff to verify if it is the FCG driving force

Julián Andrés Ortiz González, Jaime Tupiassú Pinho de Castro, Giancarlo Luis Gomez Gonzáles, Marco Antonio Meggiolaro, José Luiz de França Freire

Redundant data obtained under quasi-constant {DeltaK, Kmax} loading conditions is used to verify if the effective stress intensity factor (SIF) range DeltaKeff DeltaKmax DeltaKop is indeed the fatigue crack driving force. The crack opening…

Verification of the ΔKeff hypothesis along the fatigue crack path in thin and thick Al specimens

Julián Andrés Ortiz González, Jaime Tupiassú Pinho de Castro, Giancarlo Luis Gomez Gonzáles, Marco Antonio Meggiolaro, José Luiz de França Freire

Elber assumed that the actual driving force for fatigue crack growth (FCG) is the effective stress intensity factor ΔK_eff. To verify this hypothesis, both DC(T) and C(T) specimens are cut from a 6351-T6 Al alloy circular bar with two…

Revisiting classical concepts of Linear Elastic Fracture Mechanics - Part I: The closing ‘mathematical’ crack in an infinite plate and the respective Stress Intensity Factors

Christos Markides, Stavros K Kourkoulis

This is the first part of a short three-paper series, aiming to revisit some classical concepts of Linear Elastic Fracture Mechanics. The motive of this first paper is to highlight some controversial issues, related to the unnatural…
