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...
متن کاملA partitioned model order reduction approach to rationalise computational expenses in nonlinear fracture mechanics.
We propose in this paper a reduced order modelling technique based on domain partitioning for parametric problems of fracture. We show that coupling domain decomposition and projection-based model order reduction permits to focus the numerical effort where it is most needed: around the zones where damage propagates. No a priori knowledge of the damage pattern is required, the extraction of the ...

2. Vehicles can be designed to provide crash protection to the occu little or no penalty to the weight and cost of the vehicle. 3. Vehicle crashworthiness can be improved by providing the principles to designers and by emphasizing the importance of this design responsibility. Decisions and design choices can then be · and in cases where two or more comparable choices are possible, the in favor ...
متن کاملComputational Fracture Mechanics
The classical, overall objective of fracture mechanics is the determination of the rate of change of the shape of an existing crack. Will it propagate under given loading and environmental conditions, and, if it does propagate, at what rate and into what configuration will it do so? The corresponding computational requirement has been to obtain the fields – displacement, strain, stress, and ene...
متن کاملHigh-performance model reduction techniques in computational multiscale homogenization
A novel model-order reduction technique for the solution of the fine-scale equilibrium problem appearing in computational homogenization is presented. The reduced set of empirical shape functions is obtained using a partitioned version —that accounts for the elastic/inelastic character of the solution— of the Proper Orthogonal Decomposition (POD). On the other hand, it is shown that the standar...
