AbstractWe theoretically report the finding of a new kind of topological phase transition between a normal insulator and a topological metal state where the closing-reopening of bandgap is accompanied by passing the Fermi level through an additional band. The resulting nontrivial topological metal phase is characterized by stable zero-energy localized edge states that exist within the full gapless bulk states. Such states living on a quasi-one-dimensional system with three sublattices per unit cell are protected by hidden inversion symmetry. While other required symmetries such as chiral, particle-hole, or full inversion symmetry are absent in the system.

Proposed Model

Knowing how to deform the Turcite thermoplastic material under the action of conical penetrators is a means of obtaining information on the processing of the counterpart (made from a metal material with higher hardness) with which it comes into contact.The paper aims to theoretically determine the depth of penetration of the thermoplastic material under the action of some conical penetrators and to establish the coefficient of static and kinetic friction under the action of these penetrators. The proposed model will be validated experimentally on a tribological stand made for this purpose.

History Of

There has been a long history of applying metal to architecture. At the beginning, they just appeared in the structure of bridges, factories and storages, and then gradually turned up as a form of building structural materials in civil architecture such as markets, schools and office buildings. So all the time, metal like steel structure or hardware impresses people as a kind of industrialized building materials. With the development of architectural technology and the researching of characteristics of building materials, metal material has been brought in building skin design with brand-new appearance, and coruscate new vitality in the field of architectural design depending on full of variety of expressions and economic environmental character.
