WebbAn adaptive Picard-iteration method was developed that is able to handle the previously mentioned strongly nonlinear material laws with a reasonable computational effort. Preliminary tests indicate that this method is significantly more stable than the Newton-Raphson method that is typically used to solve this kind of nonlinearity-problem. WebbThis procedure of generating a sequence of functions which approximate the solution whose existence we are trying to establish, is called Picard iteration. Details of Picard’s …
Webb1 feb. 2024 · In the literature there are several methods for comparing two convergent iterative processes for the same problem. In this note we have in view mostly the one introduced by Berinde in (Fixed Point Theory Appl. 2:97–105, 2004) because it seems to be very successful. WebbAlgorithm for Picard iteration# The simplest method to find approximate fixed points/roots to this kind of equation consists in guessing \(x\), plugging it into the right-hand-side \(g(\cdot)\) and evaluating the function. The resulting new …
