Required Courses:

Mechanical Behavior of Polymers Topics covered in this course include linear viscoelasticity, creep, stress relaxation, dynamic behavior, hysteresis, stress-strain response phenomena, principles of time-temperature superposition, rubber elasticity, failure and fracture mechanisms for polymers, and the effect of additives on mechanical behavior. Real life design examples are used to demonstrate the topics and concepts as much as possible.

Plastics Product Design  This course reviews the theoretical principles and the engineering practice associated with the development of new plastic products. The course focuses on design pratices for products that will be produced by conventional and advanced injection molding processes. Topics include design methodology, plastic materials selection, design for manufacturing, computer aided engineering, mechanical behavior of plastics, structural design of plastic parts, prototyping techniques, experimental stress analysis, and assembly techniques for plastic parts.

Elective Courses (choose two of the following):

Polymer Structure, Properties, and Applications (3 credits) Relationships between polymer structure (chemical composition, molecular weight and flexibility, inter-molecular order and bonding, supermolecular structure) and practical properties (mechanical, acoustic, thermal, electrical, optical and chemical) and applications.

Computer Applications in Plastics  Problem solving in plastics engineering has been dramatically influenced by the computer and innovative software packages. This graduate course will focus on the application and development of software packages for engineering analyses of plastics processes. Specially, the course will cover the basic CAD programs, Pro/ENGINEER, SOLIDWORKS, followed by basic Pre-and-Post processor software, FEMAP, meshing program HYPERMESH, FEMLAB multiphysics, and MATHEMATICA.

Product Design for Elastomers  This course covers the basic of thermoset and thermoplastic elastomer product design. Topics include mechanical behavior, large deformation structural analysis, design for manufacturability, performance limitations, and end use applications for elastomers and assembly considerations.

Extrusion Die Design  This is a project-oriented course which utilizes current CAE programs to design extruder dies. This course will study the basic principles of extrusion die design and apply these principles in designing extrusion dies. A review of the extrusion process and the flow behavior of various polymers will be studied.

Machine Design  Hydraulics, machine logic, drives, pumps, motors, heating barrel and screw combinations, mechanical design. Hydraulic and electrical control circuits development. A semester project is required.

Medical Device Design I A systematic approach to inventing new medical devices. The class details the process of validating medical needs including market assessment and the evaluation of existing technologies; basics of regulatory (FDA) and reimbursement planning; brainstorming and early prototyping for concept creation. Course format includes expert guest lecturers and interactive practical discussions with faculty. Students will prepare a medical device proposal and presentation.

Medical Device Design II This course focuses on how to take a medical device invention forward from early concept to technology translation and implementation planning. Topics include technology research and development; patent strategies; techniques for analyzing intellectual property; advanced planning for reimbursement and FDA approval; choosing translation strategies (licensing vs. start-up); ethical issues including conflict of interest; fundraising approaches and cash requirements; essentials of writing a business or research plan; strategies for assembling a development team. Students will prepare a final medical device proposal and presentation.

Advanced Mold Design  This course provides an integrated approach to mold engineering which includes the interrelationships of polymeric materials, engineering principles, processing, and plastics product design. Major topics include cost estimation, mold layout and feed system design, cooling systems, structural design considerations, and ejector system design. Analytical treatment of the subject matter is given based on the relevant rheologym, thermodynamics, heat transfer, fluid flow and strength of materials.

Computer Aided Engineering and Design I  This course provides a fundamental approach to computer-aided engineering for plastics processing. Emphasis is upon the theory and techniques of computer aided engienering as applied to plastics processing problems, allowing students to understand the various assumptions and methods used to create the programs.

Computer Aided Engineering and Design II  Modeling and process simulation in plastics processing. Design of plastic components and molds. Use of finite element programs to perform flow, cooling, and stress analysis of injection molded parts.

Structural Product Design Design of plastic and composite products to meet structural requirements including strength, stiffness, impact, fatigue and creep while remaining low weight, low cost and easy to manufacture. The course will include an overview of structural properties of polymeric materials as well as application of finite element analysis to homework and project assignments.
