Nano‐Architected Metallic Metamaterial With Enhanced Fatigue Resistance via Dislocation Starvation
Advanced Materials, EarlyView.Nanoscale Ni single crystals exhibit remarkable fatigue resistance over an order of magnitude higher than that of bulk single crystals through dislocation starvation. By translating this mechanism into geometric nano‐architecture, nano‐architected Ni single‐crystal metamaterials achieve about twice the fatigue resistance of the bulk, despite their ...

Advanced Materials, EarlyView.Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...

Transient Cytoskeletal Anisotropy Encodes Short‐Term Mechanical Memory in Glioblastoma Cells
Advanced Materials, EarlyView.The same mechanical deformation can produce distinct cytoskeletal states depending on loading history. Experiments and constitutive modeling reveal that transient actin–vimentin anisotropy stores mechanical information and governs short‐term mechanical memory in glioblastoma cells.

The Tensile Strength of Elastomers
Rubber Chemistry and Technology, 1955Abstract The theory of strength proposed above appears to describe satisfactorily the effect of crosslinking on the strength of amorphous elastomers, and to apply semiquantitatively to crystallizable elastomers. Further work, involving the effect of primary molecular weight, constitution, swelling, and additives is required to substantiate the ...

A simple method is described for visualising regions of bone that have yielded in tension. The appearance of such regions is quite different from that of regions that have yielded in compression. The significance of these findings is discussed.

A new wire test specimen was developed as part of the Safe Technology consortium project to produce a nitinol algorithm for the fe-safe™ fatigue postprocessor. The requirements for the design were permit tensile and compressive loading, accommodate data collection of strains from ±0.1 to 6% at high-frequency cycling.

Tensile testing of ultra high tensile roping wire
Materials Science and Engineering, 1977Abstract Criteria for assessing cold-drawn wire quality in respect of its suitability for its use in a steel rope is discussed. It is shown that the avoidance of premature tensile failure of individual wires in a rope is to a large extent governed by its ability to elongate uniformly.

Abstract Some features of the uniform strain and of the reduction of area in the tensile test are considered. With examples from b.c.c., f.c.c. and c.p.h. metals, it is shown how the uniform strain reflects the details of their plastic deformation characteristics.

Cracks in tensile-contracting and tensile-dilating poroelastic materials
International Journal of Solids and StructuresFibrous gels such as cartilage, blood clots, and carbon-nanotube-based sponges with absorbed oils suffer a reduction in volume by the expulsion of liquid under uniaxial tension, and this directly affects crack-tip fields and energy release rates. A continuum model is formulated for isotropic fibrous gels that exhibit a range of behaviors from volume ...

Analysis of tensile test beyond the ultimate tensile strength
Journal of Materials Processing Technology, 1992Abstract The strain of tensile test specimens in the domain beyond their ultimate tensile strength was analysed by means of a tensile test machine supplemented by a television camera and computer. The work served to verify the feasibility of computing the strain parameters by a routine where the inputs are only data describing the force versus ...
