The present study is an important step in understanding the brain case as a structure. Beams taken from the layered regions of embalmed calvaria were repeatedly tested in three- point bending at various span lengths to determine the resistance of layered cranial bone to bending and shearing deflection. These beams were also strain gaged and loaded to failure in four- point bending to study the failure response of layered cranial bone. The layered beam theory used in this study was found to provide a valid relationship between the constituent material properties and structural geometry of layered cranial bone and its flexural response.
