Senior Design Project: Cyclic Pressure System

Accelerated Wear Testing (AWT) is a procedure used within the medical industry that tests the durability of material by emulating the physiological conditions found within the human body. Since the process is time-consuming and expensive, companies resort to outsourcing due to testing limitations including the magnitude of cycles and restricted access to samples. Consequently, it is incredibly challenging to get the measurements of the material’s creep and fatigue behaviors. The goal of this study is to design and develop an innovative pressurized chamber for an AWT-based cyclic stress system to test materials. Advanced techniques including Computer-Aided Designing, Computer-Aided Engineering analysis, along with additive manufacturing technology will be used to realize the proposed design concepts. The proposed testing system would address the problems in current methods including lack of both quickness and simplicity. The results of this study would not only enable users to facilitate the measurement of a material’s modalities of failure,but also allow them to perform in-line testing.
