Nanocomposites provide new properties and exploit unique synergism between materials. Polyvinylidene fluoride (PVDF) is an ideal piezoelectric matrix applicable in nanocomposites in a broad range of industries from oil and gas to electronics and automotive. And boron nitride nanotubes (BNNTs) show high mechanical, electrical and chemical properties. In this paper, the critical torsional load of...

Abstract To reduce computation time, the inherent strain (IS) method is popular. It consists in adding layers, at room temperature, with an “inherent strain” representing plastic deformation undergone during deposition. An IS developed, including a direct determination of tensor based on transient thermo-elastic-viscoplastic (TEVP) simulation. Validation achieved: taking full-field strains, all...

A study is made into the effect of the critical current density dependence upon the value of plastic strain on the critical state stability in hard and composite superconductors under conditions of plastic yield of the material. There have been found criteria of the critical state stability relative to the jointly developing magnetic flux jumps and plastic strain jerks.
