چکیده
In this contribution, an adaptive method for Model Order Reduction (MOR) is presented simulating physically non-linear material behavior of micro-heterogeneous structures. The purely online and includes a Galerkin projection, which performed using projection operator initially gained by Proper Orthogonal Decomposition (POD). By the number degrees freedom to solve decreased drastically can be projected back vector space high fidelity problem after solution process. composition follows algorithm, evaluates update if convergence not ensured during Newton Raphson scheme. Later on, simulation, controlled POD-based control criterion sorting out non-relevant basis vectors from previous updates. This results in efficient leads satisfying speedup simulation performance efficiency MOR scheme investigated numerical simulations hexagon-shaped unit cell.

Balancing for Nonlinear Systems MOR
We review a nonlinear balancing approach presented in 2000. Unlike the method introduced by Scherpen (1994), which requires the solution of PDE’s, the novel method is computationally efficient and works also for unstable systems. First, we argue that a generalization for balancing nonlinear systems should be based upon three principles: 1) Balancing should be defined with respect to a nominal f...
متن کاملAdaptive Steffensen-like Methods with Memory for Solving Nonlinear Equations with the Highest Possible Efficiency Indices
The primary goal of this work is to introduce two adaptive Steffensen-like methods with memory of the highest efficiency indices. In the existing methods, to improve the convergence order applied to memory concept, the focus has only been on the current and previous iteration. However, it is possible to improve the accelerators. Therefore, we achieve superior convergence orders and obtain as hi...
متن کاملNonlinearity-aware sub-model combination in trajectory based methods for nonlinear Mor
Trajectory based methods approximate nonlinear dynamical systems by superposition of dimensionally reduced linear systems. The linear systems are obtained by linearisations at multiple points along a state-trajectory. They are combined in a weighted sum and the combinations are switched appropriately to approximate the dynamic behaviour of the nonlinear system. Weights assigned at a specimen po...
