Fronts of reaction in certain systems (such as so-called solid flames) are modelled by a high-order nonlinear partial differential equation, which we analyse numerically. Previously, Strunin [IMA J. Appl. Math. 63:163-177, 1999] obtained stable spinning solutions of the equation using the Galerkin method. Here we use a more sophisticated and arguably more powerful method, namely the one-dimensional radial basis function method, to study the equation further. As an initial step, we elaborate the numerical code and tested it by reproducing the spinning regimes for a range of initial conditions. In a new series of experiments, we find a regime where the front is shaped as a pair of kinks spinning in a stable joint formation. The settled character of this regime is demonstrated.

“…[24] Thai and Kim 2010 present two variable refined plate theory for Free vibration of laminated composite plates. [26]The theory comprises of r parabolic distribution of the transverse shear strains through the plate thickness, and satisfies the zero traction boundary conditions on the surfaces of the plate without using shear correction factors. Hamiltopns principle is used to derive equation of motion and the closed-form solutions of antisymmetric cross-ply and angle-ply laminates are determined by using Navier technique.…”

I. INTRODUCTION A. What is a composite Material?A broad definition of composite is: Two or more chemically distinct materials that when combined has improved properties over individual materials. The composites may be either natural or synthetic. B. ApplicationThe glass-reinforced polyester has all the properties that make it ideal for this purpose and has become the standard material. Laminated plywood panels with thin layer of reinforced plastic are also widely used in truck trolleys. Various methods are used to produce them and the low cost, and the strength offered by the plywood that is attractive. They may not be as light as desired, but are found to be considerably more durable than conventional constructions, particularly under heavy duty conditions. There is also a growing market for products such as vans and trailers that are made from glass-reinforced plastic at competitive prices. Vehicles destined for consumer markets tend to be attractively designed, their appearance is different and the tools are easy. Mold reinforced plastic of the full size model of the piece are taken. The pattern can be made of wood, clay or plaster. The automotive sheet body is molded into molding molds paired with glass fiber or wick as reinforcements. Large and complex pieces can be produced and their reproduction can be made equally fast. Parts made using this technique generally have a uniform thickness, because the additional reinforcing fibers cannot be loaded easily or accurately. Composite molding materials are used when small rigid parts have to be made and are usually prepared by casting. The bulk molding compound is composed of polyester resin, glass fibers and filler. The strength is less than that obtained by other molding processes. The molding compounds may be prepared as continuous sheets. Due to the longer fibers and a high glass content, its strength is better than those made in the bulk molding method. Injection molding are used to some extent to produce materials that can be applied to structural materials. After the separate manufacture of parts by molding or other methods, the assembly of the vehicle body has to be made. Tools and accessories similar to those used in metal parts are used for drilling and drilling operations. The assembly of several parts is usually accomplished by adhesion, using resins that are catalyzed to cure at room temperature in a short time. A good bonding strength is achieved even without pressure, although fastening devices are required to locate the assembled parts correctly in relation to each other. High-build primers are used to give a high-gloss finish so that surface imperfections do not become obvious. Commercial aircraft applications are the most important uses of the compounds. Aircraft, unlike other vehicles, need to place greater emphasis on safety and weight. They are achieved using

“…The 1D-IRBFN method is much more efficient than the original IRBFN method reported in [24]. Ngo-Cong et al [25] extended this method to investigate free vibration of composite laminated plates based on first-order shear deformation theory. The present work is concerned with the development of a new numerical method to handle 2D incompressible viscous flows at a high Re number and in large scale problems.…”

This paper presents a local moving least square -one-dimensional integrated radial basis function networks (LMLS-1D-IRBFN) method for solving incompressible viscous flow problems using stream function-vorticity formulation. In this method, the partition of unity method is employed as a framework to incorporate the moving least square (MLS) and one-dimensional integrated radial basis function networks (1D-IRBFN) techniques. The major advantages of the proposed method include: (i) a banded sparse system matrix which helps reduce the computational cost; (ii) the Kronecker-δ property of the constructed shape function which helps impose the essential boundary condition in an exact manner; and (iii) high accuracy and fast convergence rate owing to the use of integration instead of conventional differentiation to construct the local RBF approximations. Several examples including two-dimensional Poisson problems, lid-driven cavity flow and flow past a circular cylinder are considered and the present results are compared with the exact solutions and numerical results from other methods in the literature to demonstrate the attractiveness of the proposed method.
