Abstract

Thermal fatigue of mild steel has received little attention until recently even though this material is used extensively in heat exchangers for gas-fired appliances. A survey of the thermal fatigue problem of thin shell mild steel structures subjected to arbitrary temperature fields is given. Data from end-constrained thermally cycled test specimens is also presented. These data have been validated through use in developing production heat exchangers.
