As the longitudinal displacements are restricted in CWR tracks, a considerable rise in temperature induces compressive stresses in the rails that can lead to track buckling. Given the nonlinear behavior of the ballast, usually represented by a linear plastic model, the problem of snap-through buckling may occur, for which only a few nonlinear analysis methods can trace the full response of the track structure. However, these methods fail to yield convergent solutions for problems with thermal loads when implemented in their conventional algorithm. For this reason, a new methodology is presented allowing the calculation of the safe temperature. In addition, some analytical results are also derived for comparison with the numerical results, obtained using three-dimensional finite element beam models provided by ANSYS. <\/jats:p>","DOI":"10.1142\/s0219455413500168","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T09:27:50Z","timestamp":1365067670000},"page":"1350016","source":"Crossref","is-referenced-by-count":20,"title":["A NEW METHODOLOGY FOR EVALUATING THE SAFE TEMPERATURE IN CONTINUOUS WELDED RAIL TRACKS"],"prefix":"10.1142","volume":"13","author":[{"given":"J.","family":"CARVALHO","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"given":"J.","family":"DELGADO","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"given":"R.","family":"CAL\u00c7ADA","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"given":"R.","family":"DELGADO","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]}],"member":"219","published-online":{"date-parts":[[2013,4,4]]},"reference":[{"key":"rf4","unstructured":"C.\u00a0Esveld, Modern Railway Track, 2nd edn.
