Figure 1 shows the prosthesis inserted into the hip.
Data
Figure 2 shows the most important geometric dimensions (in centimeters) of the implant, as well as the most risky and problematic sections from a structural strength perspective.
To simplify the analysis, the resistant sections will be assumed to be circular. The load will be assumed to act at the midpoint of the cylinder, as shown in Figure 2, with an additional safety condition of five times the person's weight. The person in question weighs 894 N (approximately 91.2 kg).
The characteristics of the possible materials to be used are found in Table 1. Note that Chromium-cobalt casting has a different behavior in compression and tension.
Determine
The maximum and minimum stresses, as well as the shear stress, to which the part is subjected in the A-A plane. Assume it is a cylinder with a diameter of 12.7 mm.
Draw the Mohr circle for the stressed state using software.
