Samples exhibited a characteristic ‘‘J’’ influence non-linear stress-strain response, with stiffness increasing with utilize strain. The cords were labe lled with rows of lesser markers and the uniaxial tension tests were recorded via video. accompanying image analysis enabled the scattering of strain on the cord surface to be determined. elastic models were developed to model the machinelike behaviour of the specimens and were found to adequately describe the material behaviour. r 2004 Elsevier Ltd.

Introduction The consider of the mechanical properties of the spinal cord is useful for the analysis and fellow feeling of the biomech anics of spinal cord injury (SCI), chronic c! ord abridgement syndromes (e.g. chronic spine disease or syringomyelia), and of the spinal cord’s response to sub-injurious loading such as those go by means of during normal motion (Yuan et al., 1998). It is perhaps surprising therefore that vicarious research has been undertaken into the mechanical response of spinal cord to loading, at either normal or abnormal physiological...If you want to roll a full essay, order it on our website: OrderCustomPaper.com
