. Finally, the simulated results of crack initiation were compared with real experimental data. The comparison presented here shows good correlation between simulations and experimental tests with respect to failure modes such as the position of cracks

. One school of industry thought held that a void in a solder joint would be a stress riser that initiated cracks, leading to solder joint failure

presence of micro cracks and surface defects such as scratches and chips. In these materials, the high level of stress at the tip of a crack cannot be relieved by plastic flow and so even very small defects can lead to low failure loads
