Abstract

The failure of a screw made of AISI 4140 steel used in the cylinder head of an internal combustion engine was determined through fracture mechanics. For the loads applied to the screw, it is observed that when this reaches a value of 2,056,565.96 N, then the theoretical axial load to which the bolt is exposed is 513,296.05 N; where it will have the greatest influence on a critical crack size of 6,2 mm. The load is distributed mainly on the first three ropes where the first occupies about 55% of the load, the second 25% and the third 15%; the maximum stress in the screw is 1 796 MPa.
