Micro Abstract:
The huge computational costs make classical Finite Element (FE) simulations of nonlinear structural problems subjected to long-term or e.g. cyclic loading a challenging task. One approach to tackle this is through Model Order Reduction (MOR). Space-time MOR leads to a low-dimensional nonlinear system of equations which is solved in coarse time intervals, e.g. for each load cycle. Thus, remarkable computational saving in terms of CPU time and memory space are attained.
