Workshop – SHAPE MEMORY ALLOYS – DESIGNING YOUR NEXT MECHANISM  

Approximate Time: 8:00 am to 5:00 pm

Location: Hilton Cleveland Downtown

Registration Price: $550

Description:

Sixty years after the discovery of shape memory alloys (SMAs), many actuation and structural applications using these materials have been conceived and developed. SMAs are a unique class of multifunctional materials that have the ability to recover large deformations and generate high stresses in response to thermal, mechanical and/or electromagnetic stimuli. These abilities have made them a viable option for actuation/structural systems in aerospace applications, amongst others. However, designing with SMAs is a paradigm shift from the conventional way we look at metals and mechanisms.

In this course, you will learn how the unique properties of SMAs can be applied to designing mechanisms and the associated benefits. Basic primer will be provided on what they are and why they work with examples of the most successful applications that have been imagined. Common design tool and properties-database will be discussed.

Learning Objectives:

Upon completion of this course, you can successfully:

  • Describe SMA operation principle
  • Apply the benefits of SMAs to mechanism design
  • Describe basic material and form selection
  • Apply SMA design tools to building hardware

Case studies

Instructor:

Materials Research Engineer in the High Temperature and Smart Alloys Branch at NASA Glenn Research Center

The instructor for this course is Dr. Othmane Benafan. Dr. Benafan is a materials research engineer in the High Temperature and Smart Alloys Branch at NASA Glenn Research Center. He received his Ph.D. in Mechanical Engineering from the University of Central Florida in 2012. Since joining NASA GRC, His work entails developing novel shape memory alloys with high and sub-zero actuation temperatures to enable new, lighter weight aerospace mechanisms and shape changing components for temperature ranges beyond the limits of commercial SMAs. His work is continuing to develop the alloys, address scale-up issues, assess durability, and develop specifications and standards, all of which are critical to enable the technology to be adopted for flight. Othmane is currently the Executive Chairman of the joint industry-government-academia Consortium for the Advancement of Shape Memory Alloy Research and Technology (CASMART), and the Vice President of the ASM International Organization on Shape Memory and Superelastic Technologies (SMST).
