Overview
This course will introduce mechanics of structure genome (MSG) as a unified framework for multiscale modeling of composite structures and materials starting from fiber/matrix scale all the way to macroscopic structural scale. This course will emphasize skills of using MSG-based online software tools to perform simulation needed for design and analysis of various types of composite structures such as unidirectional (UD) fiber reinforced composites laminates, 2D and 3D textile composite structures, and honeycomb sandwich structures. This course will use several composites simulation tools on cdmHUB (https://cdmhub.org/) which will be freely accessible for registrants.
What You Will Learn
- Challenges associated with modeling of composite materials and structures.
- Basic ideas of multiscale modeling of composite materials and structures.
- Basic ideas of MSG and the advantages of MSG compared with other approaches for modeling composite structures and materials.
- How to use MSG for micromechanical analysis of composites: predict lamina constants and 3D properties of composite laminates, failure of various types of composite materials.
- How to use MSG for modeling thin composite structures as a plate: predict ABD matrices, in-plane and flexural properties of composite laminates, equivalent plate properties for honeycomb sandwich structures, failure of composite panels, etc.
- How to use MSG for modeling slender composite structures as a beam: predict equivalent beam problems for composite rotor blades, high-aspect ratio wings, deployable booms, failure of composite slender structures.
Key Course Topics
- State-of-the-art multiscale methods
- MSG and its companion online tools
