The rotating disk has many engineering applications as in floppy, hard, compact, laser, and recently optical disk drives. This paper (Part II) considers the application of a finite element method presented in a companion paper (Part I) to the analysis of rotating disks. The critical speed of the disk is obtained to validate the problem formulation and solution method. Dynamic responses are obtained as parameterized by the rotating speed. Effects of the temperature distribution and material system are also observed. Thermal effects are crucial in the analysis of rotating disks, since the variation of temperature can be significant. This is especially true for equipment in which a heat source is used as a means of recording or erasing data and for equipment in which the amount of generated or transferred heat is significant. The specially orthotropic material properties of a laminated disk can have a large effect on the overall dynamic behavior.
