Abstract

We considered if temperature effects the growth of microcracks in a casted bro- ken femur, locally at three particularly points. We used theory of adaptive elasticity neglecting and accounting temperature and energy density theory. We showed for both cases after the removal of the cast, femur locally at points of our interest i) will be weaken (the mean length of their microcracks will be increased) or ii) will be under osteoporosis (the mean length of their microcracks will be dramatically increased). The results coincide with those of corresponding problem at macroscopic area. We resulted that temperature plays no role to growth of microcracks for our case.

Keywords:
theory adaptive elasticity neglecting and accounting temperature density energy theory microscopic area (dramatically) increased of mean length of microcracks
