Introduction The fiber-reinforced composite materials using on the reinforcement of concrete structures are now mainly carbon fiber and Kevlar.
The basalt fiber is the preferred alternative to carbon fibers and aramid fiber reinforcement materials.
Other mechanical properties of materials are stated in Table 1 and Table 2.

In plate-cone reticulated shell of composite material, the stress of cone unit is far less than intensity limit of materials, due to the low modulus of elasticity the composite (GFRP) and thinner thickness of laminated plate, local buckling is the main controlling factor for design.
Composite modeling is difficult to mould design, laminated floor layer in ANASY software, the material is to determine the coordinate direction of material attribute, by unit is the only sure, coordinate, coordinate to ensure materials determine the coordinates of the composite Shell element, the unit is default coordinate basis I - j edge coordinate system.
Considering the production cost of materials and the man-hours, overmuch layer number is unfavorable, total layer number of 4 layers is the best in the premise of reasonable laying way.

The present study is focused also in the mechanism of chloride penetration in cementitious materials.
Chloride ions penetration in cementitious materials is one of the processes widely responsible for the degradation of concrete structures.
Materials The materials used in this investigation were Portland cement, GGBS, aggregate, water and super plasticizer.
Portland cement (CPA-CEM-I / A 42.5) conforming to the Algerian standard NA 443 and GGBS were utilized as cementitious materials.

More specifically, it provides a subprogram that constructs a simplified point interaction diagram as well as a subprogram that constructs an accurate interaction diagram assuming complex nonlinear stress-strain behaviour of materials.
Nonlinear stress-strain behaviour of materials can be assumed which also contributes to higher accuracy of the interaction diagram.
The user also chooses the stress-strain behaviour, to be assumed when calculating the stresses in materials.
The publication [1] mentions that minimal eccentricity should be assumed because various geometrical and material imperfections always appear in constructed members.

According to the material and structural characters of these caves, the paper used a response surface method to calculate the structural reliability.
Because the used building material is natural raw earth to form a self-support earth-arch system, there is a great difficulty studying the property of stress and deformation.

Introduction Cold spray (CS) is a material deposition technique where metal powder particles are accelerated up to speeds of 500-1000m/s by a stream of carrier gas, and the materials are subsequently bonded to the surface of the metallic substrate upon impact.
The noticeable peak broadening in the materials of coating in comparison with material of substrate suggest most probably accumulation of some significant microstress in cold spray particles after deposition.
Since the model constants, together with elastic properties of materials, fully determine the stress state of the elastic system, this can demonstrates the model’s ability to consider both geometric and material factors.

Size dependent transport properties of nanocrystalline materials have also been investigated by Jose et al. [5].
Depressed semicircles appear due to distribution of relaxation times in these materials.
