Weakly Continuous CAD Technology for Isogeometric Analysis ID: 2015-034

This technology introduces weakly continuous CAD for streamlined integration of design and analysis, enhancing efficiency in modeling complex CAD structures.

Technology Overview

The document details the application of weakly continuous computer-aided design (CAD) technology in isogeometric analysis, focusing on its use in constructing models with non-matched intersections and parameterizations. This approach facilitates the seamless integration of design and analysis processes, significantly reducing the time and resources needed for creating analysis-suitable models. It explores this technology through three structural benchmark problems involving T-brackets subjected to horizontal traction, demonstrating improved convergence in displacement and stress solutions.
