Introduction
In fact, concrete is one of the most common materials of construction worldwide.
Previous investigations on LWC have been focusing on producing lightweight concrete using different materials including natural and manufactured lightweight aggregates and recycled materials.

Nevertheless the forces in our experiments show a typical behaviour for micro
machining and the used workpiece material (aluminium alloy AlMg3), i.e. the thrust force is
the dominant force component and the forces are in the rage of one Newton or less.
They are determined by the geometrical dimensions of the holder and its elasticity module (material: steel, E = 210kN/mm 2).
The research project was supported by the grand MA 1657/17-2 form the Deutsche Forschungsgemeinschaft (DFG) and the grant 20237-N14 from the Austrian Science Foundation (FWF).

Introduction
The potential associated with nitride-based Light Emitting Diodes (LEDs) and Laser Diodes (LDs)
for solid-state lighting has generated a continuing interest in group III-N materials and their alloys.
From that point of view, the growth temperature TG for 2D step flow growth is equal to half the melting point TM of the grown material [2].

Introduction
The current generation of textiles, including technical textiles are passive.
Generally textiles are made out of materials of very high electrical resistance and can, therefore, be considered as materials with good electrical insulating properties.
The aim of the paper is to demonstrate the development of electrically active knitted structures and switches which have resulted from the research carried out by my research group in the School of Materials of the University of Manchester, UK.
In knitting science the stitch geometry is defined with one half circle (stitch head), two straight lines (stitch legs) and two quarter circles (stitch feet).
Therefore, our aim was to create the science base to package the chip within a fibre bundle.

The test panels were constructed at 1/2 scale, with all materials the same as prototype.
The general order of ABAQUS modeling contains creating parts, defining material properties, assembly parts, setting analysis unit, defining the interactions between components, meshing, loading and determining boundary conditions.
After creation, we need to give material properties to each component through defining the "material" and "cross-section".
In this model, we adopted damaged plasticity model for masonry panel and concrete, which need to define the material properties and some other relevant parameters in plasticity definition [5-8], the value of all the parameters are shown in Table 2.

Introduction
Tissue engineering has been developed to meet the need for the repair or replacement of damaged tissues and organs, by applying the principles of biology, material science and engineering to develop artificial tissue substitutes [1-4].
Native tissues are very complex, yet highly organized, structures composed of living cells and manifold ECM materials.
