Simulation of Fatigue Crack Growth for Pearlite Structured Steel Using MATLAB

Characteristics of fatigue crack growth for ferrite pearlite structured steel for four different conditions is studied using MATLAB & to obtain the design curves for all four cases and then making a comparative study. Afterwards, parametric study is done by varying one variable at a time and graphs are generated for each MATLAB program. A comparison of fatigue crack growth of all four cases of ferrite-pearlite steel is done and results are compiled. The design curves obtained are in agreement with the literature.
