Notes:
The technical development of construction equipment such as wheel loader leads to anincrease of not only amount of workload per hour, but also magnitude of allowable stress range.Since welded structures of the wheel loader occupy approximately 40-60% of its total weight andare subjected to incessant fatigue loads, fatal fatigue failures occur occasionally around the weldedzone during its practical operation in the field. To reasonably evaluate the fatigue life, the effect ofthese geometries and welding residual stress on the fatigue life should be taken into account. In thispaper, the modified notch strain approach developed previously by the authors is applied practicallyto assess the fatigue life of welded joints in boom and front frame structures of the wheel loader
