...Solène Kojtych; Florence Nyssen; Charles Audet; Alain Batailly Over the past decade, the drive towards more efficient aircraft engines has pushed the boundaries of operating ranges far beyond a linear structural context. Nonlinear interfaces, such as blade-tip/casing contacts, are to be expected...
