Analytical study on elastic limit speed of non-uniform rotating disks considering thermal effect on elasticity modulus

摘要

This study concerns the analysis of thermoelastic characteristics of non-uniform rotating disks subjected to thermal load including the effect of inertia force due to rotation of the disk. The solutions up to the elastic limit yield stress of the material are obtained under plane stress assumption by taking variation on total potential energy. The solution algorithm is implemented with the help of MATLAB computational simulation software. The analysis is carried out for various disk geometries and temperature distribution profiles. The effect of temperature on elasticity modulus is also investigated and some numerical results are presented and discussed in the form of limit angular speed under thermo-mechanical loading and reported in dimensionless form.
