Abstract :
In this paper, stress analysis at thigh Bone that under concentrate force P is investigated
by using Michell solution. The thigh Bone is the long bone that extends from the hip to the knee. It can
break during a motor vehicle crash, fall or sports activity. The cross section of the bone is approximated
as a hollow circle. The concentrate force P is applied in the diameter direction on the bone;concentrated
force on the bone, is applicable in Surgery of the implant placement at the broken bones. At first the
concentrated force p is changed to the widespread force, this widespread force is applied to the small
region and declaration of the load on the outer surface at the series form. Finally after determining the
number of suitable sentences of series, the stress distribution is plotted. The results shown the singularity
point is under the loading point that is a reasonable result.
