- Abstract
The biomechanical response of brain tissue to strain and the immediate neural outcomes are of fundamental importance in understanding brain injury. Experimental work on measuring the strain-response of brain tissue must be completed to bridge this gap. The objective of this work was to develop and test a headform model for impact that has the capacity to incorporate porcine brain tissue. A surrogate tissue slab was used in the current work, made from silicon gel, filled with radio-opaque markers. The deformation was monitored using a high-speed in-situ X-ray cinematography system at 7,500 fps. The kinematics and strain results from impact were compared among the impact speeds. Strain progression was clear throughout the slab with increased speed resulting in increased strain levels. Repeated impacts at the same speed displayed the region-specific repeatability of the headform under impact testing
