TL;DR: In this article, various strategies to induce self-healing behavior in fiber reinforced polymer based composites are discussed and a distinction is made between the extrinsic and intrinsic healing strategies.
Abstract: This paper addresses the various strategies to induce self-healing behaviour in fibre reinforced polymer based composites. A distinction is made between the extrinsic and intrinsic healing strategies. These strategies can be applied at the level of the fibre, the fibre/matrix interface or at the level of the matrix. It is shown that the degree of healing depends on the type of damage and the testing mode used and examples are given both for extrinsic and for intrinsic healing systems. The conclusion is drawn that self-healing in fibre reinforced composites is possible yet unlikely to become a commercial reality in the near future.

TL;DR: In this paper, the authors performed tensile tests on both a non-textured and a highly textured, fully austenitic stainless steel in both the rolling and the transverse directions.
Abstract: Uniaxial tensile tests on both a non-textured and a highly textured, fully austenitic stainless steel were performed in both the rolling and the transverse directions. Both materials show mechanically induced phase transformation from the austenitic FCC to the martensitic BCC phase. Differences in overall transformation behavior are observed between the two steels. No direction-dependent transformation behavior is present during deformation of the nontextured steel. However, when a strong texture is present, differences in transformation behavior during deformation in different directions can be observed clearly. The ‘stress induced transformation’ theory, in combination with the austenite texture measured before deformation, is used to explain and model the transformation behavior when straining in different directions. The theoretical results of the stress-induced transformation theory compare well with the measured austenitic textures after deformation and the recorded stress vs martensite fraction curves.

TL;DR: In this article, the influence of process conditions on the clad layer appearance and the mechanical properties of both the layer and the substrate were investigated, and it was shown that the quality of the deposited layers was highly dependent on the process temperature.

TL;DR: In this article, the authors performed tensile tests on a highly textured, fully austenitic stainless steel in the transverse and rolling directions and found that the transformation from the austenite phase to the martensite phase occurred at a higher strain and stress and reached a lower ultimate fraction of martensites as compared to the rolling direction.

TL;DR: In this paper, the influence of progressive physical ageing on the plastic deformation behavior of unplasticised poly(vinyl chloride) (uPVC) is characterised and incorporated in the existing approach.
Abstract: The timescale at which ductile failure occurs in loaded glassy polymers can be successfully predicted using the engineering approach presented in a previous publication. In this paper the influence of progressive physical ageing on the plastic deformation behaviour of unplasticised poly(vinyl chloride) (uPVC) is characterised and incorporated in the existing approach. With the modification it is possible to quantitatively predict long-term failures which show a so-called endurance limit. The predictions are compared with failure data of uPVC specimens which were subjected to constant or dynamic loads. In dynamic loading conditions a second type of failure mode was observed: fatigue crack growth. A brief study on the influence of the frequency and stress ratio of the applied stress signal shows that crack growth failure is not expected to occur within experimentally reasonable timescales for constant loading conditions.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: Friction stir welding (FSW) has achieved remarkable success in the joining and processing of aluminium alloys and other softer structural alloys, however, it has not been entirely successful in the manufacturing of different desired materials essential to meet the sophisticated green globe requirements as discussed by the authors.
