Question

a MatLab script called "es15118assnm". The script must be well-commented so the graders can follow and grade your work) Problem Consider two long cylinders of two different types of materials where one cylinder fits inside the other one. The inner radius of the inner cylinder is a and its outer radius is b. The outer cylinder has an inner radius of b and an outer radius of The Young's modulus and Poisson ratio of the inner cylinder are El and vi, respectively, while the outer radius values are E2 and v2. The radial stress, ơrr. hoop stress, age, and radial displacement, u, are given by the following equations: o) +B, where i -1,2 ơeei (r)- + B, where i 1,2 ur(r)--atmA, + (1-ri) rB, where is),2 -A rBi When i-1, it is referring to the inner cylinder and i -2 refers to the outer cylinder. If the outer surface of the outer cylinder is subjected to a compressive radial displacement Uo and the inner surface of the inner cylinder has no radial stress, then the following four boundary conditions can be used to determine Aq.
