Congratulations to Mohammad Homayounpour, PhD Graduate of Dr. Andrew Merryweather’s Ergonomics and Safety group on his publication Cervical muscle activation characteristic and head kinematics in males and females following acoustic warnings and impulsive head forces published in Annals of Biomedical Engineering. Sex, head and neck posture, and cervical muscle preparation are contributing factors in the severity of head and neck injuries. However, it is unknown how these factors modulate the head kinematics. In this study, twenty-four (16 male and 8 female) participants experienced 50 impulsive forces to their heads with and without an acoustic warning. Both sex and warning type […]

Congratulations to PhD Graduate Nik Benko on his publication Mechanical characterization of the human pia-arachnoid complex published in the Journal of Mechanical Behavior and Biomedical Materials. In this study, Nik quantified the normal traction modulus of the pia-arachnoid complex (PaC) in five post-mortem human subjects using hydrostatic fluid pressurization in combination with optical coherence tomography. This study is the first to characterize the mechanics of the human pia-arachnoid complex and quantify material properties in situ. Data from the study suggest implementing a heterogeneous model of the brain-skull interface in computational models of TBI may lead to more realistic injury prediction. The full article can be found here: Benko N, Luke […]

Congratulations to Jiawei Yan on his recent publication The effect of impact angle and fall height on skujl fracture patterns in infants published in the Journal of Biomechanical Engineering. The objectives of this research were to utilize a newly developed linear elastic fracture mechanics finite element model of infant skull fracture to investigate the effect of impact angle and fall height on the predictions of skull fracture patterns in infants. Nine impact angles of right parietal bone impacts were simulated from three different heights onto a rigid plate. Impact angle significantly affected the fracture initiation site and orientation. Fall height significantly affected the fracture […]
