Mathematical foundations of material models like hypoplasticity and barodesy
Wolfgang Fellin, Alexander Ostermann, Gertraud Medicus
This research aims to understand the underlying mathematics, enabling the development of time integration schemes, numerical stiffness computation, and small strain extension. The investigation also explores basic properties like coaxiality and alignment, highlighting similarities and differences between the two models. Deepening mathematical understanding can facilitate model development and potentially establish connections between them.
