Tóm tắt

Notes that what applied scientists in classical continuum mechanics are doing is based on knowledge established by Newton, Cauchy, Euler, Rayleigh and others, and no really fundamental laws or principles in continuum mechanics have been “discovered” since. Newtonian mechanics provides a vital tool, which is still valid in all manners of ways from engineering to astronomy. Illustrates that we are not inventing completely new concepts of the world – rather, we are dealing with more and more precise models designed within the scope of Newtonian continuum mechanics. Nowadays, material non‐linearities, large strains and deformations, high‐velocity impact problems and others are routinely treated by sophisticated discrete tools, for example boundary elements, finite elements as expressed in Eulerian, Lagrangian and/or ALE formulations. Notes that modern methodologies are based on progress that is constantly being reported in finite element technology areas and that we should not believe in free‐energy production.
