چکیده
i=0 if(xi): (2) i.e., we express the numerical approximation to the integral I(f) as a sum of a series of nite number of terms, each term containing the value of the function at a given point xi weighted by a coe cient i. One way to determine the coe cients i is to replace the original function f(x) by an interpolating function which is simple enough, or in the terminology of numerical analysts, to use a quadrature technique. Let us explore this idea a little further:

A General Rule for the Influence of Physical Damping on the Numerical Stability of Time Integration Analysis
The influence of physical damping on the numerical stability of time integration analysis is an open question since decades ago. In this paper, it is shown that, under specific very general conditions, physical damping can be disregarded when studying the numerical stability. It is also shown that, provided the specific conditions are met, analysis of structural systems involved in extremely hi...
متن کاملNonlinear Numerical Integration Scheme in Strain Space Plasticity
Strains are applied to the integration procedure in nonlinear increments todecrease the errors arising from the linearization of plastic equations. Two deformationvectors are used to achieve this. The first vector is based on the deformations obtained bythe first iteration of the equilibrium step, and the second is acquired from the sum of thesucceeding iterations. By applying these vectors and...

In this paper, we studied the numerical solution of nonlinear weakly singular Volterra-Fredholm integral equations by using the product integration method. Also, we shall study the convergence behavior of a fully discrete version of a product integration method for numerical solution of the nonlinear Volterra-Fredholm integral equations. The reliability and efficiency of the proposed scheme are...
