Abstract
An attempt has been made to develop an expert system to facilitate engineers and researchers to predict the fatigue life of metals. Life of the specimen in terms of number of cycles could be predicted based on safe-life approach, under constant amplitude loading. The user has the option of selecting a material from the database provided or define a specific material of choice. Input is presented as material data, loading data and geometry details. Provision has been made in the expert system to estimate fatigue data using tensile data, if complete material data are not available. Life prediction method is further classified into high cycle fatigue and low cycle fatigue and in each, different methods developed by researchers are available to estimate the life. Expert system is developed using Visual C++ and more than 500 different trials have been carried out to test the results obtained. Provision has also been made to include material data to database, and also to incorporate other modules like fracture mechanics approach, damage mechanics approach and variable amplitude loading.
