Fatigue of materials refers to the changes in properties resulting from the application of cyclic loads. Basically every metal element has different limit ability. Limits of ability can be caused by mechanical properties, chemical composition and other things. Every structures always contain crack. The initial length of these cracks reasonably detect when we check or examine the structure. To asses the safe life of the structure we need to know how long (how many cycles) the structure can last before one of these cracks grows to a length which is propagates catastrophically. The purpose of this study is to find out whether different combined stress condition and stress level affect the fatigue crack growth and the lifetime of a material. This experimental study is to find out materials life estimation for fatigue crack growth and damage tolerant, with knowing the age of materials after the crack, in the future we can estimate the life time of the material after several cycle due to load dynamic. Based on data result on this experiment, stress level is greatly affect the fatigue lifetime of a material. The higher the stress level will produced faster crack to initiate and propagate. The higher the value of the combined stress, the slower crack will initiate, propagate and the fatigue lifetime will get longer. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini!
