The goal of themed entertainment is to use activities and environments to tell a story and immerse the guest in a novel experience. By applying these concepts to nonfiction and educational topics, the concept of edutainment is created. In recent years museums have begun utilizing the concept of edutainment and techniques typically found in themed entertainment experiences to capture the attention and focus of guests and create experiences that connect emotionally with them. My goal in this thesis pathway project was to investigate this trend and technique of connecting with an audience and apply it to the STEAMtank project within ASU’s Innovation Space. The goal of STEAMtank is to design and fabricate children’s STEAM museum exhibits in two semesters with focus on accessible design. My team conducted research and interviews exploring current market trends in theme parks and museums, best practice designs and operations, and interests of children to develop the concept for our exhibit, Gust of Dust, which was then fine-tuned, constructed, and installed in the STEAMtank Exhibit Space. Gust of Dust is an exciting exhibit demonstrating the power of a haboob that was developed from preconcept to installation in under a year by two determined and talented interdisciplinary teams. Learning about haboobs connect concepts of environmentalism, earth science, and safety to real concepts in children’s lives.
In real world applications, materials undergo a simultaneous combination of tension, compression, and torsion as a result of high velocity impact. The split Hopkinson pressure bar (SHPB) is an effective tool for analyzing stress-strain response of materials at high strain rates but currently little can be done to produce a synchronized combination of these varying impacts. This research focuses on fabricating a flange which will be mounted on the incident bar of a SHPB and struck perpendicularly by a pneumatically driven striker thus allowing for torsion without interfering with the simultaneous compression or tension. Analytical calculations are done to determine size specifications of the flange to protect against yielding or failure. Based on these results and other design considerations, the flange and a complementary incident bar are created. Timing can then be established such that the waves impact the specimen at the same time causing simultaneous loading of a specimen. This thesis allows research at Arizona State University to individually incorporate all uniaxial deformation modes (tension, compression, and torsion) at high strain rates as well as combining either of the first two modes with torsion. Introduction of torsion will expand the testing capabilities of the SHPB at ASU and allow for more in depth analysis of the mechanical behavior of materials under impact loading. Combining torsion with tension or compression will promote analysis of a material's adherence to the Von Mises failure criterion. This greater understanding of material behavior can be implemented into models and simulations thereby improving the accuracy with which engineers can design new structures.
