Study of reduced-order modeling techniques for augmented reality applications

In a world that is becoming more digital and online, powerful computation strategies can be used to performtest and simulations that reduce the design and validation costs of new products. However, standard FE computations require a lot of resources to provide accurate results and are based on a fixed system where every time the conditions of the problem change all the process has to start over. This thesis combines a solver methodology for periodic structures based on the creation of reduced-order modeling and domain partition with a 3D interactive interface. The first part alleviates the computational cost of the solving process to boost up the algorithm to provide real-time results while the second part provides on the one hand an interactive pre-process where the load conditions can be modified at any time and on the other hand an interactive post-process able to display the results in real-time. Therefore, this thesis aims to develop a computer application to set up the bases for real-time structural tests that are ready to use augmented reality tools to display the results in an approach more understandable and user friendly. The results extracted from this work demonstrate the viability of real-time interactive simulations using this approach without the need of extremely powerful processors which allows executing these tests in home-use computers. Hence, this thesis provides the base of a powerful computation engineering tool affordable to the majority of the users
