Authors have made a fatigue strength data-base FRINT in the late 1970's and after that developed KAFASAS for the purposes of a common data use and an easy data management. Several fatigue strength data-bases have been developed since then and used in the fields of fatigue strength design and research but most of them impose difficulties on users to modify data structure and renew data.
On the other hand, a remarkable progress has been made in hard and soft-ware of computers. Low cost, high speed and powerful personal computers, as well as multifunction data-base soft ware are now available for designer and researcher.
In this paper the construction of fatigue strength data is reviewed, and a personal fatigue strength data-base allowing any user to construct and modify the data-base and renew the data is shown. This data-base which contains about 1200
S-N curves on metallic material operates in the environment of any personal computer using the data-base soft ware “Microsoft Excel”.
