It also has emphasized the importance of validation of these results on the determination of loads collapse of structural elements, as is reflected positively in the field of Structural Engineering in the face of increasing advancement of surface modeling programs and technological innovations in according to sustainability criteria for constructions materials.
And last, but not least, to the Laboratório de Estruturas and Laboratório de Materiais de Construção do Departamento de Engenharia Civil da Universidade do Minho, the Laboratório de Materiais de Construção and Laboratório de Caracterização e Processamento de Materiais da Universidade Presbiteriana Mackenzie by the experimental campaign.

It is determined that the developed composite materials are promising for use in elements and friction units of wind power plants and shipbuilding engineering objects.
Each stage of the life cycle of any product requires separate consideration, including from the point of view of the possibility of making changes to the design, based on the needs of the end customer, or to extend the life of individual units, assemblies, structures in general; or to adapt structures to new civil and military trends, in particular for the successful development of the Arctic region [2].
Currently, the widespread use of titanium in various branches of mechanical engineering is due to the fact that it has such properties as corrosion resistance, fatigue fracture resistance, high specific strength, low modulus of elasticity, low density, cold resistance, and others.
The achieved high characteristics indicate the possibility of a significantly wider range of application of the developed coatings than for elements of wind power plants of an Arctic coastal location, primarily in ship engineering, in elements of pipeline and ventilation fittings, deck structures, support blocks, etc.

All binders except 100%L:0%C could be used in any masonry, rendering, plastering and pointing application because they exhibited compressive strengths in the range of 0.4 to 2.5 MPa after 28 days curing period. 1.0 Introduction Concrete is one of the most commonly used construction materials which largely affects the overall cost of buildings and civil engineering structures [1,2].
Cement reduction in construction industry translates to reduction in cost of construction and emission of CO2 gas. 5.0 Recommendation Having exhibited the highest compressive strength after 28 days curing period, it is recommended that the blend of 40%L:60%C be adopted to replace cement in mortar production for masonry, rendering, plastering and pointing applications References [1] Amankwah, E.O., Badiako, M., Kankam, C.K.

Sometimes it is required to create engineering structure with dielectric, nonmagnetic and other special properties, i.e. when the application of steel reinforcement is restricted.
Longitudinal Bend Test of Fiberglass-Concrete Pipes Fiberglass-concrete pipes can be used as various engineering structures (supports of telecommunication and power supply lines, posts of industrial and civil buildings, hollow-shell piles, bridge and viaduct pillars, trestle pillars etc.).

But, it is evident that to find this numerical method is important and necessary for several application units such as the mechanical or civil engineering.
In solid mechanics, the finite element method [4] (FEM) is a well known, versatile, flexible numerical method that is being used extensively in almost all fields of science and engineering.
