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...
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...
Another interpretation could be made by focusing on the network structure. In the present network, the cross-linker molecules reacted with the COOH side groups of the precursor polymers not only in an intermolecular manner, but also in an intramolecular manner, according to the discussion of the...
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...
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 ...
(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 ...

The stress focusing effect in a solid sphere and an infinitely long solid cylinder under instantaneous uniform heating at the free surface is studied on the basis of the generalized thermoelastic theories, that is, Lord-Shulman and Green-Lindsay theories. The combined governing equations of both ...
