For inertial loading in frontal impacts, the effects of the neck muscles are profound, and impact the accuracy of computational and physical surrogates. Previous studies have shown two important aspects of muscle modeling in adult computational models are muscle attachment location and muscle loading lines of action. The objective of the current study was to evaluate techniques for modeling muscle curvature in adult computational neck muscles using data from cadaveric dissections and MRI, and to investigate the changes in overall head/neck response when using different muscle wrapping techniques. Dissection based muscle paths were modeled using multiple linear muscle strands, which resulted in curved loading lines of action similar to the MRI derived muscle paths. Six of the 12 muscles had a portion of their paths, (on average 25±14% of the path length), that were significantly different from the MRI derived paths. Muscles that incorporated muscle wrapping with sliding contact interactions resulted in the highest correlation to volunteer kinematic corridors in a 15 G frontal impact. This curvilinear muscle response should be included to improve model response for frontal impact with muscle activation.
