TL;DR: In this paper, the contour method is extended to the measurement of multiple residual-stress components by making multiple cuts with subsequent applications of superposition, and the theory is experimentally tested on a 316L stainless steel disk with residual stresses induced by plastically indenting the central portion of the disk.

TL;DR: In this paper, a systematic experimental study and numerical simulations have shown that the theoretical prediction of the strength and actual failure mechanism of these sandwich structures can be affected by significant errors, specially in the presence of prevalent shear loading.

TL;DR: In this paper, it is shown that superposition of stresses measured post-cutting with results from the contour method analysis can determine the original (pre-cut) residual stresses.

TL;DR: In this paper, a numerical-experimental study of double-lap joints between aluminum and carbon fiber reinforced polymer (CFRP) laminates has been carried out, which highlights both the static and the fatigue performance of such joints obtained by using aluminum and steel rivets, as well as known the particular damage mechanisms related also to premature localized delamination of the CFRP laminate due to the riveting process.

TL;DR: In this article, a method for the high-cycle fatigue life prediction of components subjected to gaussian, stationary, wide band random loading is presented, which can be applied to random stress processes having PSD of any shape, and the fatigue life predictions obtained are more accurate than that provided by most of the frequency domain techniques proposed in literature.
