Abstract: High performance electromagnetic (EM) absorbing materials are highly desired for aerospace and defense applications such as aircraft engine nozzles and their aerodynamically heated parts. Typical EM absorbing materials consist of high concentrations of iron powders in polymer matrix, however, are heavy and costly. Carbon materials, e.g., carbon nanotubes (CNTs), carbon black, and graphite flakes, can only be used in air for limited temperature applications (<400oC). For higher temperature and oxidizing environments, such as the airplane nozzle areas, wing tips,…

Abstract: High cycle fatigue (HCF) is the dominant failure mechanism of many engineering applications. For fatigue life predictions safe-life and damage-tolerance approaches have been used extensively, however, they are limited due to the empirical nature. These limitations can be addressed by performing direct numerical simulation of the fatigue loading history using computational methods such as the finite element method (FEM). The time scale associated with the fatigue problem especially in high cycle fatigue (HCF) applications is the main challenge for…

Abstract: Ohio Northern University (ONU) is a founding partner of KEEN (the Kern Entrepreneurial Engineering Network).   This talk will give an overview of efforts at ONU to achieve our vision of saturating the student experience with the entrepreneurial mindset.  Topics will include: Why we think this matters to ONU and to undergraduate engineering education What tools we have implemented to try to make this easier for faculty What is has meant for a new faculty member starting in the…
