ICADA : Integrated Computer Aided Design and Analysis

Vitenskapelig sammendrag

The project will target the proof of concept in relation to the whole engineering process: The modelling (CAD), if necessary, the transition to a suitable engineering model (CAE), the generation of a discrete analysis model (FEM) where grid generation isa key issue, to the extraction and presentation of results. Isogeometric analysis: Connecting design and analysis The main focus in the project will be on building knowledge and competence for integrated computer aided design and analysis in structural mechanics, i.e. isogeometric analysis of load carrying structures relevant in civil, mechanical and naval engineering. In particular, we will address stiffened thin walled structures. Adaptive methods: Combining efficiency with reliability By encouragingdesigners to make topological consistent CAD-models, we aim for enhancing the competence in Norway to do goal oriented adaptive finite element analyses in order to strengthen the competitiveness of the relevant academic and industrial sectors in Norway. Prototype programs: Provide proof of concepts The ICADA project will provide proof of concepts i.e. demonstrate that designers may make topological consistent CAD-models for seamless transfer to FEM-packages. Furthermore, we will develop prototype software for the FE-analysis part as well as the visualization step, suitable for exploitation in commercial software packages. Vertical integration: Emerging technology tested on industrial relevant problems Together with our industrial partners the isogeometric framework will be tested on real world applications relevant for Norwegian industry.

Populærvitenskapelig sammendrag

Det har blitt utviklet et programbibliotek kalt IFEM for bruk av splines i design og analyse. Programbiblioteket inneholder rutiner for simulering av 2D og 3D tynnveggede og massive konstruksjoner. IFEM håndterer problemstillinger med store forskyvninger og ikke-lineære materialoppførsel, samt adaptiv forfining basert på Locally Refined B-splines (LR B-splines). Det er også utviklet en prototype for visualisering av isogeometriske (splinebasert elementmetode) analysedata.
