Course Overview

This course has been designed to provide basic understanding of the fundamental issues regarding the design of injection-molded plastic parts (especially those used in automotive applications) to avoid undesirable outcomes and failure. It aims to provide basic knowledge of injection molding process and design for efficient manufacturing and performance. Characteristics and properties of commonly used plastics (especially those used in automotive components) are related to their process and performance characteristics. For this purpose, discussions on part defects (i.e., sink, flow line, stress concentration, etc.; their causes and design methods to avoid them are provided. Recent advances in process, design and testing methods are also covered. The course provides complete information on process variables and how they impact the part, as well as quality control processes and the ability to troubleshoot the process.

The topical coverage for the “Plastic Part Failure Analysis” course can be summarized in the Course Outline below.

Instructor Biography:

Dr. Erol Sancaktar received his Ph.D. (Eng. Mechanics) and M.S. (Mech. Eng.) degrees from Virginia Tech. He is a Fellow of ASME and has served as Chair of ASME Tech. Committee on Reliability Stress Analysis, and Failure Prevention (1997-2008, 2013-present). He served as Associate Editor for the ASME J. Mech. Design (1995-2006) and Medical Devices (2006-2013). He was a faculty member at the Mechanical Eng. Dept. at Clarkson University during 1978 to 1996 before joining Univ. Akron in 1996 as Professor of Polymer Eng. He was also appointed Professor of Mechanical Eng. in 2009. Dr. Sancaktar currently holds the title, Professor Emeritus at the University of Akron’s School of Polymer Science and Polymer Engineering (since August 2020). Prof. Sancaktar edited 25 books and Journal Special Issues, authored 111 refereed journal articles, 30 articles in books edited by others, including 2 chapters in ASM Engineered Materials Handbook, as well as two chapters in Handbook of Adhesion Technology by Springer. He delivered 244 technical presentations and has 4 patents. Dr. Sancaktar organized 30 Conferences.

Dr. Sancaktar served in 15 different Federal Government review panels and served as reviewer for numerous scientific research proposals, journal articles and books. He had over 18 consulting assignments, sabbatical and extended visits with various government agencies (i.e., NASA, U.S. Army), industrial establishments (Kendall Co., Chrysler Corp.), foundations and legal agencies, not counting one-day consulting/advising visits. Among these expert services was an over-billion-dollar case and expert witness testimony at the U.S. International Trade Commission (2017).

Prof. Sancaktar and co-workers obtained ~ $4M Research and Grant support with 56 projects during 1980-2022. These include 8 National Science Foundation grants (~ $1.1M and spanning over 25 years), 3 Teaching Grants and 20 projects sponsored by Industry.
