3-DAY COURSE: FUNDAMENTALS OF THREADED FASTENERS & JOINT DESIGN FOR ENGINEERS AND DESIGNERS
Dates: Rescheduled to Oct. 13 – 15, 2020
Location:
TBD – Chicago
Credit: The course is worth 21 Professional Development Hours (PDHs)
Course Overview
Participants in this course will be taught the fundamentals of threaded fasteners, the purpose of different part features and embodiments, and the importance of material, heat treating, and plating and coating choices. The course will provide an overview of fastener failure modes and specific steps which can be taken to avoid them. The course will explain why fastener preload is all-important to joint performance. Participants will be introduced to joint diagrams and be provided guidance on what preload scatter the designer can expect in the fastener after the effects of relaxation caused by embedment and thermal effects. Participants will be taught how to use a Simplified Bolted Joint Design Guideline which defines a systematic method for evaluating bolted joints in a clear and understandable manner.
The course includes case studies and problems which will be solved during class and hands-on demonstrations of preload scatter obtained through torque tightening and excessive bearing stress.
Although the VDI-2230 standard will often be referenced, the course is not intended to provide a detailed presentation of this standard.
