Compressing thin sheets usually yields the formation of singularities which focus curvature and stretch on points or lines. In particular, following the common experience of crumpled paper where a paper sheet is crushed in a paper ball, one might guess that elastic singularities should be the rule...
The stress-focusing effects are analyzed in an exact manner, and a clear indication of the mechanism of thermal and phase transformational stress-focusing effects in a transversely isotropic spherical Zirconia inclusion in the isotropic infinite elastic domain is given.doi:10.1080/714050875...
Focusing on the change in the shape of the entire monolith material according to the increase in the γ value from 1.0 to 1.8, it is observed that the formation of continuous structures began to partially break down for γ greater than 1.4. The monolith sheets prepared at γ = 1.8 ...
In particular, Fujita and Ueda [9] showed that elastic interactions between dislocations could reduce the required critical stress for this formation compared to the aforementioned model. Fig. 13 shows that interaction between two dislocations with opposite Burgers vectors slipping on two closely spaced...
By using XRD and 2D elastic-plastic FEA, Hattori et al. calculated the residual-stress distribution through the thickness of cold rolled aluminum sheets [21]. Under low friction conditions, compressive residual stresses were found on the surface that change to tensile ones in greater depth. The ...
(Fig.2b), which suggests that hydrogel–GNR can endure larger stresses. This impressive phenomenon imparts hydrogel–GNR with larger strength and elastic modulus arising from increased mechanical stiffness (Supplementary Fig.9)36. As a result, the hydrogel–GNR holds considerable potential in ...

In this paper a phenomenological model is proposed to describe the situation, which involves a dynamic martensitic transformation in a spherical particle of Zirconia embedded in an infinite elastic matrix. Following the ray methods, we clarify the stress-focusing effect caused by the instantaneous ...
In addition, according to Ref. [57], in its 2016 study, it took into account new research on machine learning in relation to COVID-19 was conducted, focusing on the usefulness of machine learning. Therefore, the techniques based on machine learning (ML) and Deep learning (DL), have been...
The lap shear test results are reported as average shear stresses at failure, but it is the stress concentration that is of interest in design (which is far greater than the average stress). The lap shear test results can be back-analysed using an elastic stress analysis that is consistent ...
