The first problem involves a homogeneous variable profile disk, whereas the second one is a functionally graded disk having a variation in elasticity modulus. For the variations of disk thickness and elasticity modulus in these problems, a new form of nonlinear function controlled by three parameters is introduced. The derivations of the closed form solutions for both type of rotating disk problems are carried out in a unified form. The closed form solutions are verified numerically by the nonlinear shooting method.eninfo:eu-repo/semantics/closedAccessFunctionally graded materialsRotating diskVariable thicknessArticleQ1Q1402133152WOS:000303125800001
