Fatigue Crack Propagation in Polycarbonate

Journal of the Society of Materials Science, Japan, 1970
Various studies have so far been made of fatigue crack propagation about all kinds of engineering materials, but as its essential mechanism has not yet been known an experiment was performed on plane bending fatigue test using a Polycarbonate plate for specimen, and the same is reported hereunder in this paper.The relation that the differentials of the

Ultra‐Improved Interfacial Strength Between Metallic Surface and Polyurethane via Cost‐Effective Anodizing Process

Advanced Materials Interfaces, EarlyView.
SAA significantly enhanced Al/PU bonding, increasing SLSS by up to 920% and fracture energy by 15 100% through optimized micro‐nano porous surfaces. RSM identified the optimal anodizing conditions, while ML confirmed sulfuric acid concentration and roughness as dominant predictors of strength.

Fatigue Crack Initiation and Propagation [PDF]

, 2019
The resistance of metal alloys to fatigue can be classified into four major regimes: low-cycle fatigue (or short life), limited resistance (between 10^5 and 10^6 cycles), high-cycle fatigue (between 10^6 and 10^7 cycles) and gigacycle (more than10^7 cycles).
