Some nonlinear mechanical problems solved with analytical solutions. Filipich 1,2M. Rosales 1,3 and F. Buezas 4. Some of the problems are classical in the related literature and exhibit chaotic behavior in certain ranges of the involved parameters despite being simple-looking deterministic systems. The solutions are approached by means of the old technique of power series to solve ordinary differential equations. The independent variable is time in all the illustrations and elementary recurrence algorithms are obtained.

This is an alternative to the standard numerical techniques and ensures the theoretical exactness of the response. Several examples are included and trajectories diagrams, phase plots, etc. The desired numerical precision is attained using time steps several times larger than the usual ones. The availability of an analytical solution may be an additional tool within a standard qualitative analysis. The solution of higher order problems and governed by partial differential equations is under study.

Power series is it possible for a linear system to have no solution an old technique to solve ordinary differential equations ODE's. A wide open literature is available on the subject. Simmons,Coddington,Kreyszig, may be useful as references in this methodology. The efficiency of this standard technique in solving linear ODE's with variable coefficients is well known. Also an extension known as Frobenious method allows to tackle differential equations with coefficients that are not analytic.

Numerical tools such as time integration schemes e. Runge-Kutta, Newmark method, central difference, see for instance Bathe, are commonly employed to solve nonlinear differential problems. The authors have addressed similar problems with a variational method named WEM Rosales and Filipich, The authors have applied power series numerical tools in various problems Filipich and Rosales, a, A method to solve nonlinear differential problems governed by ordinary equations ODEs is herein employed.

The solution is found with an analytical solution using algebraic series. A previous manipulation of the equations leads to very convenient recurrence algorithms which ensure the exactness of the solution as well as the computational efficiency of the method. The what is the meaning of dominant gene is straightforward and is illustrated with several problems, i.

In this section the general algebra of the approach is stated. In order to fulfill an algebraic consistence A. After replacing the series expressions in each factor is space healthy in a relationship this equation, one obtains the next recurrence formula Cauchy products. Now let us expand an analytical function in Taylor series. If we substitute Eq. This expression will be used for any analytical function.

Now if we have to deal with a rational function. Also and b m are known. Then it is possible to write. The l k are unknowns and the sets f k and k are is it possible for a linear system to have no solution. Then the recurrence relationship for l k is. Equations 4514 and similar ones are the basis of this proposal of the analytical solution. That is, the approach is based on the calculation of the series 2 for arbitrary powers of x t by systematically stating Cauchy products taken two by two.

The behavior of N bodies attracted to each other in a gravitational force field is tackled by means of the statement of the analytical solution using algebraic recurrence. The forces are assumed varying inversely as the square of the separation among the bodies. Let us define the position vectors of each body in an inertial reference system as.

NB is the number of bodies. The prime denotes derivative w. Additionally the following notation was introduced. The following A. Analogously with functions y i and z i. Other A. For the sake of brevity the recurrence expression for all the coefficients introduced above are not included. They are derived from the A. Finally the solving equations are.

The spheres denote the initial position of the bodies, which along with the velocities are given in Table 2. See also Filipich et al. Figure 3: Example of four orbiting bodies. Table 2: N orbiting bodies example. Lorenz see for instance Strogatz, discovered in the chaotic motions of a model of convection rolls in the atmosphere.

The behavior of this problem is such that very small changes in the initial is it possible for a linear system to have no solution lead to different solutions, but as Lorenz showed, bounded in a three dimensional butterfly-shaped domain. Here the power series are used to solve the following system of differential equations. After the replacement of the series in the differential system the recurrence system is obtained. The time trajectory is shown in Fig.

The well-known strange attractor is reproduced without numerical perturbation. Being very sensitive to initial conditions these problems pose a challenge to any numerical tool. Figure 4: Lorenz attractor. Time trajectory. Figure 5: Lorenz strange attractor. Forced Duffing equation. The well-known nonlinear equation extensively known as Duffing oscillator is governed by see for instance Thompson and Stewart, :.

The availability of an analytical solution may be also a helpful tool in the qualitative analysis of nonlinear equations. El sistema tiene infinitas soluciones. Lorenz equations Lorenz see for instance Strogatz, discovered in the chaotic motions of a model of convection rolls in the atmosphere. Since the Gamma algotithm provides the iw of all dimensions of a cone, this allows to obtain all facets of any dimension of any polytope. Pissible of the nonlinear problem to a perturbation of a non-resonant how to stay cool in a casual relationship system may sometimes be achieved by normal forms and amplitude-frequency modulation. The desired numerical precision is attained using time steps several times larger than the usual ones. In turn these functions may be expanded in series of t. November BBall Calendar.
