Design of Pneumatically Actuated Torsional Loading for High Strain Rate Testing

Description

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

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.

The Difference Engine at Arizona State University developed the Women’s Power and Influence Index (WPI) in order to combat the systemic inequality faced by women in the workplace. It aims to analyze data, such as Equal Employment Opportunity data, from various Fortune 500 companies to provide a measure of workplace inequality as well as encourage these institutions to adopt more equitable policies. By rating companies based on what truly matters to women, ASU’s Difference Engine hopes to help both women in existing career paths as well as women seeking a new career or position in companies. However, in order for the WPI to become a relevant scoring metric of gender equality within the workplace, we must raise awareness about the issue of gender equality and of the index itself. By raising awareness about gender inequality as well as inspiring companies to further equality within their workplaces, the WPI will serve to have an integral role in increasing gender equality in the workplace. Our approach for raising awareness utilizes two different strategies: (1) establishing a new version of the WPI website that is both informative and aesthetically pleasing and (2) generating social media content on TikTok that appeal to a variety of audiences and introduce them to the WPI and our mission.

The effects of temperatures found commonly along the supply chain were explored when interacting with dendritic identifiers of various common materials. Regression analyses showed that there was no statistical significance in relating SIFT correspondence values to the surface temperature of the dendrites. Physical inspection helped evaluate the integrity of specific material and substrate combinations along with possibilities for improvement in key point designation within SIFT and ORB image recognition software.
