THREE DIMENSIONAL FINITE DIFFERENCE SOLUTION FOR THERMAL STRESSES IN RAILCAR WHEELS

Numerical solution is presented for both transient temperature and three-dimensional stress distribution in railcar wheel resulting from simulated emergency brake application; computer program was written for generating thermoelastic solutions and results include effect of shear stresses caused by axial-radial temperature gradients and high degree of boundary irregularity associated with this type of problem; program has been validated by computing thermoelastic solutions for thin disks and long cylinders, computed values being in good agreement with closed form solutions.
