TL;DR: In this article, the static and fatigue strengths of self-piercing riveting are considerably higher than those of resistance spot welding, and the fatigue strength of mechanical clinching is similar to that of resistence spot welding.

TL;DR: In this article, double-lap joints were tested both quasi-statically and in fatigue across the temperature range experienced by a jet aircraft and two variants on the double-strap joint were tested.
Abstract: Fibre reinforced polymer composites (FRP's) are often used to reduce the weight of a structure. Traditionally the composite parts are bolted together; however, increased weight savings can often be achieved by adhesive bonding or co-curing the parts. The reason that these methods are often not used for structural applications is due to the lack of trusted design methods and concerns about long-term performance. The authors have attempted to address these issues by studying the effects of fatigue loading, test environment and pre-conditioning on bonded composite joints. Previous work centered on the lap-strap joint which was representative of the long-overlap joints common in aerospace structures. However, it was recognised that in some applications short-overlap joints will be used and these joints might behave quite differently. In this work, double-lap joints were tested both quasi-statically and in fatigue across the temperature range experienced by a jet aircraft. Two variants on the double-l...

TL;DR: In this paper, a zirconium-based BMG, BMG-11 (Zr−10Al−5Ti−17.9Cu−14.6Ni, at), was tested in vacuum and air.
Abstract: Early fatigue studies on bulk metallic glasses (BMGs) have indicated fatigue strengths lower than anticipated. It was suspected that environmental effects degraded the fatigue life. In the present study, a zirconium-based BMG, BMG-11 (Zr–10Al–5Ti–17.9Cu–14.6Ni, at.%), was tested in vacuum and air. This comparison was made to define any detrimental environmental effects due to water vapor on the fatigue lifetime of BMG-11. The limited results obtained so far suggest that water vapor in air does not affect the lifetime. Moreover, the fatigue endurance limit for BMG-11 in air was found to be quite high, 907 MPa, and comparable to, or better than, those of many conventional high-strength alloys.

TL;DR: In this article, the effect of cyclic loading frequency on pseudoelastic behavior and low cycle fatigue of shape memory alloys (SMAs) is investigated, and a new strain energy based fatigue model is proposed, and validated by experiments performed under different load ratios.

Journal ArticleDOI
TL;DR: In this article, a model for the calculation of S/N-curves is presented, which takes into account the stress gradient to define the local stress limit, the number of cycles at the fatigue limit and the slope.
