The strain behavior of 0.71 Pb(Mg1/3Nb2/3)O3-0.29 PbTiO3 (PMN-PT) single crystal prepared by a solid-state growth method was investigated on two most widely used orientations, i.e., (001)- and (011)-oriented. A special emphasis put the correlation among longitudinal transverse strains consequent volume change. We show that seemingly different (011)-oriented crystals has same origin, underlying ...

We report the first measurements of mass gain and expansive strain in clay ceramics immediately following firing. The results show that both mass gain and expansive strain follow a well defined two-stage process, each stage of which is linear with (time)1/4, with a transition from the first to the second stage commencing at t ∼ 1.5 h. The first stage mass gain and strain rates are ∼3.5 times gr...

Introduction: Grooved terrain on Ganymede records an episode of extensional tectonics and possibly cryovolcanism [1], but the cause of groove formation remains uncertain. With little evidence for surface contraction to balance out extension, various mechanisms have been proposed to increase the interior volume of Ganymede and thus cause global expansion. Global expansion may be caused by the in...

The objective of this work was to determine the effect of composition on the local transformation strain in NiTi single crystals. Using in situ digital image correlation to obtain full-field strain measurements, we revealed that increasing Ni concentration and precipitate volume fraction results in smaller local transformation strains. Comparison of the local strain measurements to theoretical ...

The temporal evolution of surface strain, resulting from a combination of normal and tangential loading forces on the fingerpad, was calculated from high-resolution images. A customized robotic device loaded the fingertip with varying normal force, tangential direction and tangential speed. We observed strain waves that propagated from the periphery to the centre of the contact area. Consequent...

Currently, research on structural health monitoring systems is focused on direct integration of the system into a component or structure. The latter results in a so-called smart structure. One example of a smart structure is a component with integrated strain sensing for continuous load monitoring. Additive manufacturing, or 3D printing, now also enables such integration of functions inside com...
