Abstract

 

Although the idea of derivatives seems to be rather rudimentary, it has a profound impact on forming one of the building blocks in science and engineering. Over the years, scientists have tried to elaborate on it through different methods.  Approximate solution of the governing differential equations of many physical fields requires the evaluation of derivatives at discrete points in the domain.  Their solution becomes challenging due to the presence of higher order derivatives, abrupt change in behavior, nonlinearity and multi-scale resolution arising from characteristic parameters.  In a quest to address these computational challenges, peridynamics enables the evaluation of derivatives of any order in a multi-dimensional space, and provides a unified approach to transfer information within a set of discrete data, and among data sets. It enables the computational solution of complex differential equations in the presence of jump discontinuities or singularities.  This presentation will demonstrate the applicability of peridynamics for the solution of many fundamental and engineering problems as well as failure prediction in structural materials under complex loading conditions.

 

Biography: Erdogan Madenci is a professor in the Department of Aerospace and Mechanical Engineering at the University of Arizona.  He received his Ph.D. in Mechanical Engineering in 1987 from UCLA.  Prior to joining the University of Arizona, he worked at Northrop Corporation (1983-1985), The Aerospace Corporation (1985-1988), The Fraunhofer Institute (1989). Also, he worked at the Royal Institute of Technology (1996), NASA LaRC (2003) and Sandia National Labs (2011) as part of his sabbatical leaves.  He is the lead author of three books: (i) Peridynamic Theory and its Applications (ii) The Finite Element Method and Applications in Engineering Using ANSYS, and (iii) Fatigue Life Prediction of Solder Joints in Electronic Packages with ANSYS.  His research led to the publication of 250 journal and conference papers.  Recently, he started the Journal of Peridynamics and Nonlocal Modeling (Springer) as the Co-Editor-in-Chief.  Also, he is a Fellow of ASME and an Associate Fellow of AIAA.
