It is a persistent problem in organic light-emitting diode (OLED) display devices that the efficiency of blue-light source materials is lower than that of green- or red-light source materials. To address this problem, numerous studies have investigated bl
This paper proposes the ‘skin effect’ of the machining-induced damage at high strain rates. The paper first reviews the published research work on machining-induced damage and then identifies the governing factors that dominate damage formation mechanisms
