In the recent past, several researchers have successfully modeled the complex fatigue behavior of planar twin-roll cast AZ31B alloy sheets. Complex components are usually hot-bent, whereby the microstructure in the hot-bent areas changes significantl

Mechanical fatigue tests of unnotched, notched, and bending twin-roll cast AZ31B magnesium alloy specimens are performed in which strain fields are analyzed with digital image correlation. Clearly, delimited macroscopic bands of twinned grains (BTGs)

In this research paper the microstructure of the magnesium AZ31B alloy is investigated after the application of a single monotonic compressive strain of −0.4%. A band of twinned grains is observed to form in the test bar approximately 10 mm wide, c

Microstructural investigations and mechanical fatigue tests with in situ optical strain field measurement were performed on unnotched, notched, and bending AZ31B magnesium specimens. Twinned and twin-free regions are clearly delimited and compressive

Fatigue testing of materials under various loading conditions is an important basis for designing high performance structures. One common load state is bending that can be often found for thin walled components like sheet metal structures. For this p

Notched AM50 sheet metal specimens with four different stress concentration factors are tested under quasi-static and cyclic uniaxial loading, and the results are analyzed and compared with those of unnotched specimens. Special attention is given to

Wrought magnesium alloys typically reveal strong basal textures and thus, non-symmetric sigmoidal shaped hysteresis loops within the elastoplastic load range. A detailed description of those hysteresis loops is necessary for numerical fatigue analyse

Within this study, the lightweight potential of thin-walled closed hat members, partially supported by hollow cores, consisting of glass foam granulate and a two component epoxy resin, is investigated. Nonlinear finite element analyses are applied to

The deformation behavior and the fatigue life of AM50 magnesium alloy sheet metals under variable amplitude loading were determined experimentally via strain-controlled tests. Hysteresis loops were recorded precisely to evaluate its shapes and to cal

The present work investigates the deformation behaviour of strongly textured AZ31B wrought magnesium sheets under monotonic as well as cyclic mechanical loading. Of special focus is the distribution of strain, which is investigated employing optical
