ABSTRACT In the field of massive and complex manufacturing we are now in need of materials, whose properties can be manipulated according to our need. Smart materials are one among those unique materials, which can change its shape or size simply by adding a little bit of heat, or can change from a liquid to a solid almost instantly when near a magnet. These materials include piezo-electric materials, magneto-rheostatic materials, electro- rheostatic materials, and SHAPE MEMORY ALLOYS (SMA’s). The unique properties are made possible through a solid state phase change, that is a molecular rearrangement, in which the molecules ...
Smart Materials • Materials with coupled properties in two (or more) physical domains that are used to sense or control behavior • Physical domains? • Mechanical • Electrical - Thermal - Ferroelectrics • Magnetic - Piezoelectrics - Shape Memory Alloys (SMA) - Electrorheologic - Thermal expansion • Magnetic • Multiferroic - Ferromagnetic SMA - coupled ferroelectric and - Magnetostrictives magnetostrictive domains - Magnetorheologic • Ionic gradient (”Nastic”) • Optiical • Pneumatic Artificial Muscle Example of Physical Domains Output Input Current Magneti- Strain Temper- Light (charge) zation ature Electric Conductiv field ity Magnetic Permeabil field ity Stress Elastic Modulus ...
Learning objectives By the end of this session, participants will be able to: Define growth mindset Understand the importance of growth mindset for formative assessment Feel familiar with the research base in this area Use actionable strategies to promote growth mindset with students Train other adults using the materials provided Growth mindset: What is it? Fixed mindset Growth mindset Fixed mindset Growth mindset “I failed “Maybe I because need a I’m new dumb.” strategy.” “If I have to “Trying try hard, harder I’m not makes you smart.” smarter.” Growth mindset: ...
