Reduced order modeling strategies for computational multiscale fracture

Computational Methods for Reduced Order Modeling

This paper deals with computer aided generation of reduced-order models for fast static and dynamic simulations of micro electromechanical systems. Following previous work, we present improved methods to reduce the computational effort of parameter extraction techniques, to consider multiple electrodes and the extension of analysing capabilities. A micromirror example will be used to demonstrat...

Model Order Reduction in computational multiscale fracture mechanics

Nowadays, the model order reduction techniques have become an intensive research field because of the increasing interest in the computational modeling of complex phenomena in multiphysic problems, and its consequent increment in high-computing demanding processes; it is well known that the availability of high-performance computing capacity is, in most of cases limited, therefore, the model or...

Improved Reduced Order Modeling Strategies for Coupled and Parametric Systems

Improved multiscale computational strategies for delamination

The virtual testing of delamination is a goal shared by many practitioners, especially in the aeronautical field. In order to reach such an objective, two research topics which have undergone drastic changes over the last twenty years must be linked: the relevant modeling of composites and the efficient analysis of structures. Indeed, there have been many advances toward a better understanding ...

Reduced Order Computational Continua

INTRODUCTION The paper presents a new multiscale framework that is both mathematically rigorous and practical in the sense that it has been successfully applied in aerospace, automotive and civil engineering industries. The “rigor” aspect of the method is provided by recently developed computational continua (C) formulation (Fish and Kuznetsov, 2009), which is endowed with fine-scale details, i...
