Pseudoelastic Shape memory alloys (SMAs) are very attractive for passive vibration control due to their ability to sustain and retrieve large amounts of strain, dissipate high levels of energy and provide a restoring force to the system. They can be effectively used to attenuate vibrations of a primary system by introducing variable stiffness, and providing additional energy dissipation due to hysteresis. Motivated by these properties, this paper presents a dynamical investigation of a passive damping device, where the main elements are pseudoelastic SMA wires. The device, a mass connected to a frame by two SMA wires, was subjected to a series of continuous sinusoidal acceleration functions in the form of a sine sweep. Frequency responses and transmissibility of the device were analyzed for the case where the SMA wires were pre-strained at 4.0% of its original length. The temperatures of the wires throughout the dynamic tests were also recorded. In addition, numerical simulations of a single-degree of freedom SMA oscillator were conducted to corroborate experimental results. A thermodynamical constitutive model for SMAs was used to simulate constitutive pseudoelastic response of the SMA elements.

College of Engineering where she oversaw outreach, recruiting, retention and enrichment programs for the college. Since 2013, she serves as the Executive Director for Industry and Nonprofit Partnerships with responsibilities to increase opportunities for undergraduates engineering students to engage in experiential learning multidisciplinary team projects. These include promoting capstone design projects sponsored by industry, developing the teaching the Engineering Projects in Community Service course, and developing curricular and co-curricular programs at the Engineering Innovation Center which promote innovation and entrepreneurship among engineering students and in collaborations with other colleges on campus and partnering with other institutions across the country. Rodney Boehm has joined the Engineering Academic and Student Affairs (EASA) team as an Industry Mentor with very broad experiences, including the creation of a telecommunications standard for the fiber optics industry that is still in use internationally over 25 years later, a wide variety of business experiences in an international company, and start up experience that have helped him hone his ability to quickly determine a direction and execute to it.He is also formerly the Chief Operating Officer for GroundFORCE, a company that specializes in a unique patented construction technology. His extensive experience in running sales, marketing, manufacturing, c American Society for Engineering Education, 2016Paper ID #15857 and large multi-national organizations was applied to introducing this new technology to the construction industry. Prof. Prasad N. Enjeti, Texas A&M UniversityPrasad Enjeti (enjeti@tamu.edu) is a member of Texas A&M University faculty since 1988 and is widely acknowledged to be a distinguished teacher, scholar and researcher. He currently holds the TI-Professorship in Analog Engineering and Associate Dean for Academic Affairs in the College of Engineering. His research emphasis on industry-based issues, solved within an academic context, has attracted significant external funding. Up until now, he has graduated 29 PhD students and 11 of them hold academic positions in leading Universities in the world. He along with his students have received numerous best paper awards from the IEEE Industry Applications and Power Electronics Society. His primary research interests are in advancing power electronic converter designs to address complex power management issues such as: active harmonic filtering, adjustable speed motor drives, wind and solar energy systems and designing high temperature power conversion systems with wide band-gap semiconductor devices. Assessing Impact of Makerspaces on Student LearningAbstract In today's global market, advances in manufacturing processes and technology in general have transformed innovation and allow industries to prototype new product ideas more rapidly and less expensively than ever before. As a result, product development processes are changing drastically; engineering graduates will benefit...
