Document from the year 2017 in the subject Engineering - Computer Engineering, University of Hertfordshire, language: English, abstract: The finite element method (FEM) is one of the most known simulation method that estimate and analysis behaviour of system and structure in defining conditions. Researchers work has been finished in the field of numerical modelling in the last twenty years ago that provide engineers today to predict the simulations very close to real problem. Hence, nonlinear phenomena have existed standard modelling task in structural phenomena such as nonlinear material behaviour, deformation, contact problems. The result of the development of the software technology, simulations performs with millions of freedoms and eliminate the time consuming and cost.
