This study investigates the potential to acquire multiple fatigue data points during one vibration bending test. The original specimen used for vibration bending is a plate that applied fatigue strains to a large portion of the specimen, while only being used to assess fatigue cracks as small as 1-3mm. The Bruns-Zearley hybrid system remedied this problem by using a small insert specimen and a carrier plate. This study sought to find out if the efficiency gained can be further optimized by increasing the number of inserts attached to the carrier plate through computational modeling in Solidworks and Ansys. Based on these simulations, adding a second specimen would theoretically allow for more cycles in the same amount of time without compromising the carrier plate, but exceeding this amount would pose undue risk to the integrity of the carrier plate and pose challenges in monitoring system changes.
