| Abstract Scope |
In this study, a review of conventional, accelerated, and future concept creep test methods will be performed. Creep is a time-dependent deformation which grows over decades and can contribute to failure. Conventional creep tests are performed in real-time necessitate years to decades of testing to gain useful understanding. To enable creep resistance design, numerous replicated tests are required that span the design stresses and temperatures of interest. There is need to develop accelerated creep tests that reduce the time to capture creep resistance and that make reasonable predictions of the long-term conventional response. In this study, a historical review of conventional and accelerated creep test methods will be performed; followed by progress and future concepts that offer greater acceleration. The implication of ACTs for screening the creep resistance of designer materials built by additive manufacturing will be discussed. |
