Increased conductor section will lead to increased material use, increased steel consumption for iron tower and increased project investment.
Therefore, on the one hand, aluminum material is saved; on the other hand, conductor weight and working strength are reduced.

Most of the unusual features of transition metal carbides (TMCs) in particular depends on occupancy of number of d-electrons and to reveal these properties, several first principles calculations have been conducted in the recent and past with regards to the bulk properties of these materials particularly for the properties categorizing for niobium carbide among refractory materials, which are usually associated with typical covalent character [13].
Methodology and Computational Details The properties of materials determined by the interactions of electrons and nuclei and its description can be represented by well known Schrödinger equation.
There are different codes to implement the DFT to find the different kind of properties such as structural, energetic, electronic excitations, dynamical properties of materials.

Deans and Richards [7] suggested back face strain compliance technique for CT specimen and the technique have been widely used to evaluate crack length during material tests.
However, at the practical point of view, it can be said that the accuracy of 1/16 of span length would give enough information to engineer who evaluate structural safety.

Introduction AML is a type of automated manufacturing system, which can automatically machining, transport and store work pieces in production process, and commonly consists of several machine tools, material handling systems, auxiliary devices, control systems.
Generally speaking, tool life is affected by many factors, such as material, greasing, cooling, regrinding etc., but has the characterization of relatively fixed wear rules for a set of parts.

The key observation is that both methods not only show the variation of normal condition but also give a strong appearance of damage after sample point 180 when the different levels of induced impact are introduced.
The overall conclusion of this study into damage detection in composite materials can be regarded as positive.

This class of materials exhibit advantageous characteristics like good corrosion resistance, good mechanical properties and low cost but with lower shape recovery compared to NiTi, limiting their widespread use in engineering [2].
For 1 ECAE pass sample, the grain size is the key factor for the improvement of total shape recovery degree.
