A damage-based model is introduced to analyze crack trajectory in the solder joints.
Finally, we present the results of detecting the synthetically produced crack trajectory as well as the relevant strain fields.
More importantly, the predicted crack trajectory is demonstrated to agree very well with the experimentally observed trajectory.
Fatigue crack trajectory and also the crack growth curves versus number of cycles of load, are extracted.
Three prominent regions of a fatigue crack are investigated separately: crack tip, crack trajectory and crack initiation.
The crack trajectory was influenced by the weld's yield strength mismatch which promoted deviation towards the soft material (base metal).
