From digital imaging to fully-automated adaptive analysis of materials and structures

Digital imaging and 3D printing are increasingly being applied in the design and manufacturing in the fields of civil, mechanical, material, biomedical and other disciplines of engineering and science. Conventional computational methods for structural analysis require great human efforts to convert design models created by these technologies to numerical models and to achieve results of desired accuracy.

This research aims to develop a full automatic approach to perform damage analysis of materials and structures directly from digital images. Work could involve the development of novel algorithm for the creation of numerical models from point clouds, digital images and stereolithography models, adaptive stress analysis using the scaled boundary finite element method, and development of graphical user interfaces for pre- and post-processing. Computer code for automated structural analysis will be developed on a high-performance computing facility.

Strong analysis and computing skills are required for this project. Experience with high-performance and cloud computing is high desirable.
