Most of the available knowledge regarding the influence of corrosion on fatigue strength exists for constant amplitude loading resulting in Woehler-lines. However, the fatigue behaviour under spectrum loading, resulting in Gassner-lines, and simultan

Current experiences show that a non-proportional loading of ductile materials such as wrought steels, wrought aluminium or wrought magnesium alloys, not welded or welded, causes a significant fatigue life reduction under an out-of-phase shear strain

EN AC-42000 T6 (A 356 T6) is the most frequently used cast aluminium alloy for automotive safety components. Under non-proportional normal and shear stresses, fatigue life is increased in contrast to ductile steels where life is reduced. This behavio

Fatigue life of magnesium laserbeam-welds (AZ31 and AZ61 alloys) was assessed experimentally under variable amplitude loadings. The specimens were subjected to load-controlled cyclic loadings. The tests were carried out using a Gauss-distributed ampl

Different theories for the fatigue life estimation under variable amplitude loading were analysed and compared based on experimental test of specimens of the steel HC340LA. Some of the most representative models and damage parameters were selected: T

In the automotive sector, the cumulative damage calculation method generally applied is the Palmgren–Miner-Hypothesis with its modification according to Haibach (steeper slope of the SN-line after the knee-point) as a means of also including the da

In cases where lightweight designs are particularly in focus, effective fatigue strength improvement techniques like high-frequency mechanical impact (HFMI) treatment can be successfully implemented. Proper HFMI treatment helps overcome the strength
In the present paper, the critical distance method was used to evaluate the fatigue behaviour of magnesium welded joints. The main objective of the study was to determine the applicability of the critical distance method and to compare the findings w

A simple procedure is proposed for estimating the SN-line for the failure criterion of fatigue life to crack initiation of components not subjected to a surface treatment. The prerequisite is the availability of a SN-line for total failure, i. e. rup

The cumulative damage calculation method generally applied in the automotive sector is the Palmgren-Miner-Hypothesis with its modification according to Haibach. In several design codes the theoretical Palmgren-Miner damage sum D th = 1.0 is still rec
