A REVIEW OF ELASTO-PLASTIC STRESS ANALYSIS OF RAILCAR WHEELS
Analysis of presssure distribution when a loaded wheel rolls on a straight track involves a complex mixed boundary value problem. A large number of three-dimension finite element models are considered for elasto-plastic appraisal of the wheel. Separate investigations should be made for mechanical and thermal loads and the load-time history should be approximated by a small number of artificially linearized segments. A method is suggested for validation of the computer program.
