Bone is a interwoven material with a multiphase heterogeneous and eolotropic small structure. Bone weaken analysis attempts at predicting the stroke of musculoskeletal structures using several mechanisms and at polar shipment conditions. The hierarchic structure of bone spans from nano-scale to micro-scale with a composite bod be of nano sized material crystals in an organic matrix thence resultin g in several toughening mechanisms. These mechanisms can stop, slow or turn crack growth thus resulting in massive make out of plastic deformation before the actual failure. and then bone behaves non linearly before failure. Stress Intensity divisor has been apply in umpteen studies to characterize the mechanical lieu of bone but it does not account for the capacity washed-out in plastic deformation before the actual fracture. gum frankincense it has been found that Elastic Plastic Fracture Mechanics and J Integral approaches are more appropriate and they account for readiness spent during both elastic and plastic deformation. Also numerous other factors like age, bone thickness, load direction and carry account for the failure of the bone. The present study analyses all these financial standard and accounts towards incorporating the effect of all these factors on bone fracture and its prevention. 1.1 Introduction The divination of bone fracture due to diff erent types of loading has been a topic of i! nterest from...If you want to go about a enough essay, order it on our website: OrderCustomPaper.com
