Seminar: Material Characterization and Modeling for Structural Analysis

Innovation in materials has always been a significant driving force for the advancement and improvement of mechanical systems in industries such as aerospace, automotive, and civil engineering among others. New materials and manufacturing methods are developed to meet ever-growing demand for lighter weight, stronger bonding, and higher fuel efficiency. Meanwhile, simulation-based virtual testing has been increasingly utilized to reduce costs in product development, especially with the increasing complexity of mechanical systems. These new developments in materials demand further and more comprehensive characterization, from traditional mechanical testing for constructing constitutive and damage models, to predicting fatigue and failure, to identifying surface properties such as friction and wear. Models can be created and validated with obtained test data. However, there exists a gap between what we can learn from the tests and what we can apply and integrate in models. This presentation will discuss some projects that bridges the gap to develop methodologies for more efficient testing and accurate simulation.
