INSTANTANEOUS RESPONSE OF ELASTIC THIN-WALLED STRUCTURES TO RAPID HEATING

A generalized modelling and analysis approach of thermally induced coupled vibrations of elastic thin-walled configurations with arbitrary open cross-sections are presented in conjunction with a unified implicit transient methodology. Limited research which takes into account the influence of rapid thermal heating effects on structures involving various forms of coupling appears in the literature. As a consequence, the dynamic response of such thin-walled structures of arbitrary open cross-section to rapid heating are described here. Effects involving triple, double, and no coupling between bending and torsional vibrations caused by sudden heating on these structures are examined. Numerical test cases are presented which describe the influence of sudden heating on elastic thin-walled structures of arbitrary open cross-sections.
