A new Track of Fatigue crack growth in Aluminum Alloy (2219) under Cyclic Stresses
Journal of Techniques
A study of new Track of Fatigue crack growth in aluminum alloy (2219) under cyclic stresses has been made. It was found out that this crack grow and propagate in three phases, the first phase though the grain size (micro-structure short cracks(MSC)), second phase cross the boundary of the grain size to about 1mm in length (physically short cracks (PSC)) and the third phase up to the final fracture (Length cracks(LC)). In addition, two programs were designed on MATLAB to perform the computedoi:10.51173/jt.v2i4.259 fatcat:g3tep5srhndujgmoerpkottph4
