Abstract: Scale plays a vital role in science and engineering. Modeling and simulation at multiple scales, including multiple length scales and multiple time scales, becomes a challenge in many engineering applications. In this seminar, two types of multiscale methods will be introduced. One is hierarchical (or sequential) mutliscale modeling, and the other is concurrent multiscale modeling. A few examples will be used to demonstrate multiscale modeling and simulation in Engineering applications: material properties of nanomaterials, mechanical behaviors of nanodevices, material phase changing problems, and lubrication in mechanical systems.
