TL;DR: In this paper, the static and fatigue strength of mechanically clinched and self-pierce riveted joints in aluminium alloy sheets were compared with those of a resistance spot welded joint.

TL;DR: In this article, shot peening is assessed as a potential method for improving the fatigue strength of titanium aluminide alloys based on γ(TiAl) and metallographic characterization was performed with regard to surface roughness, microhardness, residual stress profiles, and structural changes occurring in the subsurface region.

TL;DR: In this article, the long-term mechanical behavior of polysilicon tensile specimens under tension-tension cyclic loading was investigated, and the use of an external actuator allowed the variation of the test frequency between 50 and 6000 Hz.
Abstract: The long-term mechanical behavior of 3.5 μm thick and 50 μm wide polysilicon tensile specimens under tension–tension cyclic loading was investigated. The use of an external actuator allows the variation of the test frequency between 50 and 6000 Hz. It was shown, that the strength of the samples decreases with an increasing number of cycles. The tensile strength of σ c =1.1 GPa of virgin samples was reduced by about 35% to a fatigue strength of σ f =0.70 GPa after 10 9 cycles. No influence of frequency of the fatigue behavior in the range of 50–6000 Hz was observed.

TL;DR: In this paper, shot-peening (SP) treated specimens of two types of ductile cast iron (ferrite-pearlitic ductiles cast iron, FPDI, and pearlite ductiles, PDI) were investigated from the viewpoint of crack behavior and residual stress change.
