TL;DR: The plastic deformation around a notch tip within ductile single crystal material was investigated experimentally as mentioned in this paper, and the results of tests conducted on copper and copper-beryllium single crystals were compared to analytical solutions, numerical calculations, and prior experiments on samples of Orientation I with a notch on the (1 0 1) plane and its tip along the [ 1 0 1 ] direction.
Abstract: The plastic deformation around a notch tip within ductile single crystal material was investigated experimentally. Moire microscopy was used to measure the strain field on the surface of bending samples of Orientation II with a notch on the (0 1 0) plane and its tip along the [ 1 0 1] direction. The results of tests conducted on copper and copper–beryllium single crystals are compared to analytical solutions, numerical calculations, and prior experiments on samples of Orientation I with a notch on the (1 0 1) plane and its tip along the [1 0 1 ] direction. Distinct sectors with sharp sector boundaries are observed in experiments as were predicted analytically by Rice (Mech. Mater. 6 (1987) 301). However, Rice predicted that both Orientations I and II would give rise to the same sectors. It is found that experimental results for these two orientations differ and neither set of results agree with the analytical solution. In both orientations, the sector boundaries do not exclusively correspond to angles at which slip and kink can occur in these crystallographic orientations. The experiments also lead to the conclusion that some sectors in the deformation field remain elastic even after large amounts of deformation have occurred elsewhere. Based on the optical observations and strain measurements, a stress field is presented for Orientation II.

TL;DR: In this paper, a conceptual and mechanical model is proposed to explain the development and evolution of the complex fault pattern in which it is proposed that faulting is primarily controlled by the development of volumetric instability in Triassic Evaporites due to dehydration processes during burial.

TL;DR: The existence of three dimensional corner point effects in the vicinity of a corner point where a crack front intersects a free surface was investigated in the late 1970s by Bažant and Estenssoro as discussed by the authors.

TL;DR: In this article, a forward numerical model was used to analyse the intra-plate stress field in an area of active extension of continental lithosphere, namely the Aegean region.
Abstract: We use a forward numerical model to analyse the intra-plate stress field in an area of active extension of continental lithosphere : the Aegean region. Recent tomographic images of the Hellenic subduction zone offer the unique opportunity to address the relation between the evolving Aegean stress field and temporal variations in the subduction process. To this extent we apply our model to both the present-day and the Late Pliocene situation. Regarding the current situation it is found that subduction-related forces largely explain the observed pattern of tension. Results obtained for the Pliocene indicate that detachment of the slab subducted below western Greece may have controlled the observed temporal variation in the pattern of tension.
