Summary of Recent Research
Recent research has been in the area of web mechanics and material characterization at the micro-mechanical level. This research involves the development of models for the successful transport of webs through the various manufacturing processes without incurring material defects, machine downtime, and product loss. The approach is to model existing and proposed web transport processes from first principles of mechanics. The work includes characterization and simulation of statistical variations in material properties across the web and numerical modeling to simulate a range and distribution of mechanisms that cause material defects and product loss during web transport.
