Model Order Reduction; Domain Decomposition Methods; Fracture Mechanics
Abstract :
[en] In this paper, we propose to couple model order reduction techniques with domain decomposition meth-
ods for the solution to parametric problems of fracture. The nonlinear nature of the problems requires
the use of a system approximation method to speed-up the assembly of the non-linear opreators. We
show that the method efficiently computes a solution faster than a full order model for a given accuracy.
The speed-up increases with the problem size.
