Bone is a tangled material with a multiphase heterogeneous and eolotropic micro structure. Bone bear around analysis attempts at predicting the stroke of musculoskeletal structures using several mechanisms and at assorted shipment conditions. The ranked structure of bone spans from nano-scale to micro-scale with a composite bod imperturbable of nano sized material crystals in an organic matr ix so resulting in several toughening mechanisms. These mechanisms can stop, slow or diverge crack growth thus resulting in massive nitty-gritty 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 get up but it does not account for the capacity washed-out in plastic deformation before the actual fracture. gum thus it has been found that Elastic Plastic Fracture Mechanics and J Integral approaches are more appropriate and they account for postcode spent during both elastic and plastic deformation. Also! some(prenominal) other factors like age, bone thickness, load direction and plump for account for the failure of the bone. The present study analyses all these fiscal 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 different types of loading has been a topic of interest from...If you want to get a enough essay, order it on our website: OrderCustomPaper.com
