Analytical modelling of thermal residual stresses and optimal design of ZrO2/(ZrO2+Ni) sandwich ceramics
Wenbin Zhou, Rubing Zhang, Shigang Ai +2
The joining of ceramics with metals have been extensively used in applications requiring high strength and excellent heat insulation. However, evaluating the residual stress genera…
Analytical method to determine flexoelectric coupling coefficient at nanoscale
Hao Zhou, Yongmao Pei, Jiawang Hong +1
Flexoelectricity is defined as the coupling between strain gradient and polarization, which is expected to be remarkable at nanoscale. However, measuring the flexoelectricity at na…
Magnetic Field Tunable Small-scale Mechanical Properties of Nickel Single Crystals Measured by Nanoindentation Technique
Hao Zhou, Yongmao Pei, Daining Fang
Nano- and micromagnetic materials have been extensively employed in micro-functional devices. However, measuring small-scale mechanical and magnetomechanical properties is challeng…
Electric-field-tunable mechanical properties of relaxor ferroelectric single crystal measured by nanoindentation
Hao Zhou, Yongmao Pei, Faxin Li +2
Electric field dependent mechanical properties of relaxor ferroelectric material Pb(Mn1/3Nb2/3)O3-PbTiO3 are investigated with the nanoindentation technique. Giant electric-field-t…
Multi-field nanoindentation apparatus for measuring local mechanical properties of materials in external magnetic and electric fields
Hao Zhou, Yongmao Pei, Hu Huang +3
Nano/micro-scale mechanical properties of multiferroic materials can be controlled by the external magnetic or electric field due to the coupling interaction. For the first time, a…
External uniform electric field removing flexoelectric effect in epitaxial ferroelectric thin films
Hao Zhou, Jiawang Hong, Yihui Zhang +3
Using the modified Landau-Ginsburg-Devonshire thermodynamic theory, it is found that the coupling between stress gradient and polarization, or flexoelectricity, has significant eff…
