The artery inner and outer diameters are 15mm and 20mm, respectively. The blood pressure is 100mmHg. Use thin wall theory to calculate hoop stress in the wall by using average radius. Please discuss about radial stress in the wall. Use thick wall theory to program with Matlab to calculate the radial and hoop stress distribution in the wall. Plot distribution of these stresses on the wall. Assume no longitudinal stress and no outer wall pressure. (1 mmHg=133 Pa)
