Blast-induced traumatic brain injury (TBI) has been recognized as a “signature injury” since the military operations in Iraq and Afghanistan [1]. Experimental studies using head surrogates, animal models and postmortem human specimens, combined with computational method have been widely used to understand the mechanism of blast-induced TBI and develop prevention strategies [2–4]. Among these methods, computational models of human head are an effective means for studying the complex mechanical response of the head and identifying regions of interest that may merit additional histological examination. However, the head models are usually oversimplified without considering its subtle anatomical features [4]. The goal of present study is to investigate the role of frontal sinus on the intracranial response of head models in a specific shock tube environment.

Two dimensional plane strain finite element models of human head under shock loading was developed using commercial software ABAQUS (Dassault...
