Lisätietoja toteutuksesta

The main objective of this course is to provide engineers who use computer codes, graduate students, and researchers with an extensive review of FE based numerical models and solution algorithms for nonlinear mechanics. It presents the current state-of-the-art in finite element modeling of nonlinear problems in solid and structural mechanics, and their coupling with thermal fields. It will illustrate the difficulties (and their solutions), which appear in a number of applications from mechanical, aerospace or civil engineering and material science. All the sources of nonlinear behavior are present in a systematic manner, related to kinematics, equilibrium, constitutive equations, or boundary and coupling conditions. Special attention is paid to dealing with a class of problems with nonlinear constitutive behavior of materials, large deformations and rotations of structures and instability problems with either material (localization) or geometric (buckling) nonlinearities, which are needed to fully grasp any weakness of a particular structural design near the ultimate limit state. In addition, multi-physics models will be addressed, with a special emphasis of thermal coupling and fluid-structure interaction.
