Investigation Of Small Remotely Piloted Aircraft System (Srpas) To Human Head Impact, Yuhu Weng
Investigation Of Small Remotely Piloted Aircraft System (Srpas) To Human Head Impact, Yuhu Weng
Electronic Thesis and Dissertation Repository
Small remotely piloted aircraft system (sRPAS) to ground human head impact could cause injuries to the public. Skull fractures and brain injuries have been observed in sRPAS-related impacts, which varied in angles, locations and velocities. This study developed a representative quadcopter sRPAS finite element model and incorporated it with THUMS ver 4.02 50th percentile male and 5th percentile small female models to simulate sRPAS to human head impacts. The simulations were validated with cadaver experiments. The common injury metrics such as head injury criteria (HIC) and brain injury criterion (BrIC) were correlated with head injury-related responses such as …

Developing Multi-Species Brain-Strain-Based Scaling Law Using Finite Element Analysis., Xingyu Liu
Electronic Thesis and Dissertation Repository
To better understand traumatic brain injury (TBI), various laboratory animal experiments have been developed. However, there lacks an effective scaling to connect animal TBI models with human brain injuries. With the help of the finite element (FE) model, brain mechanical responses such as strains can be predicted, and hence can serve as a parameter to facilitate animal to human scaling, as these tissue-level strains directly link to neuronal damage. In this thesis, first, a comprehensive comparison of brain strains between animal TBI models and human TBI cases was conducted. Then, a brain-strain-based scaling law between mouse and human was developed, …
Biomechanical Analysis Of Commotio Cordis In Children's Baseball - A Computational Approach, Grant J. Dickey
Biomechanical Analysis Of Commotio Cordis In Children's Baseball - A Computational Approach, Grant J. Dickey
Electronic Thesis and Dissertation Repository
Commotio cordis is the second leading cause of cardiac death in young athletes. This rare sudden-death mechanism most commonly affects young children playing baseball. It is caused by impacts to the chest during the repolarization phase of the cardiac cycle, which causes the heart to go into ventricular fibrillation, often leading to death. This study adopted the detailed and validated CHARM-10 child finite element model to replicate commotio cordis instances by simulating baseball impacts to the chest. New commotio cordis injury metrics were developed to create a more accurate prediction for chest protector effectiveness. The conventionally used injury metrics for …
