Computer Simulations: Advances in Research and Applications

by Michael D. Pfeffer (Author, Editor), Erik Bachmeier (Editor)

Computer Simulations: Advances in Research and Applications begins with a concise overview and background of the topic during the past decade. The finite element method and the commercial available codes are introduced with an emphasis on Abaqus as the mostly used software in this field. The next part deals with the tire geometry and creation of a consistent and computationally effective finite element mesh from 2D and 3D drawings. The material models used for the description of the mechanical behavior of tire constituents are also examined. The following paper is dedicated to the computer simulation modeling as a method of solution of differential games where analytical investigation is problematic. The main idea is that a very small number of scenarios including both control variables and parameters can provide a sufficiently good qualitative representation of dynamics of the modeled system. The Tablot Effect, which was first experimentally observed by Henry Talbot in 1836, is discussed. It is the repeated self-imaging of a diffraction grating at regular distances in the near-field behind the grating. If the observed diffraction images are laid out as a function of distance, a beautiful and repetitive pattern is observed; this is known as the Talbot carpet. The methodology of how the IFIM method was applied for the simulation of Talbot effect is described explicitly followed by a systematic synthesis of the Talbot carpet from the generated data. The authors go on to present a numerical study of the unsteady airflow characteristics inside a solar chimney power plant. Lastly, the book presents an aggregation procedure for hydrogen permeability experiments precluding depressurization and (or) change of the samples of investigated material. Additionally, the corresponding mathematical software for correct processing of measurements along with appropriate assembly of the experimental unit is described
