Recently, robust implicit energy and momentum conserving algorithms have been developed in the non-linear range. The authors extended these algorithms to hypoelasticity­ based constitutive models and introduced numerical dissipation, opening the way to more com­plex simulations such as blade-loss in a turbofan.
