This report reviews the information in the literature on thermal strains and stresses in ships as well as theoretical methods of analysis which may be applied thereto. Localized heating by the sun has been observed in a number of ships. Almost no observations of temperature effects have been made on ships under the weather conditions and sea temperatures which prevailed at the time of serious ship failures. Evidence was found in connection with brittle fractures of Group I severity that thermal stresses may have been a significant factor in the failure of at least thirty tankers and an equal number of dry cargo ships. In some of these cases thermal stresses were the prime factor. In the remainder, heavy weather or other elements were also contributory. Theoretical methods were found which would predict with fair accuracy the nominal thermal stresses and deflections in the hull girder of a ship if the distribution of temperature were found which would yield actual rather than nominal stresses. The small amount of information on the subject of thermal stresses applicable to ships indicates the desirability of more research in this field.
