2. Objectives and learning outcomes
2.1 Objectives
The modeling of different materials is one of the most difficult questions of mechanics. This lecture explains the basic (micro and macro) physical reasons of the different material behaviors, starting from the elastic state until the (plastic and/or fracturing) collapse. It introduces the thermodynamical principles of the constitutive equtaions, explains the different micromechanical and phenomenological modeling of material behaviors and their numerical applications for the different finite element simulations too.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
  1. A general theoretical overview about the different versions of engineering material models and the knowledge of the applicability of these models in the engineering design processes.
B. Skills
  1. The correct application of the material models in the different engineering problems,
  2. The knowledge of the conditions of the good applications.
  3. The ability of the selection among the advantageous or/and disadvantaged material models.
C. Attitudes
  1. Individually creates linear and nonlinear elastic, elasto-plastic and fracturing material models in case of practical engineering problems.
D. Autonomy and Responsibility
  1. Endeavors to discover and routinely use the tools necessary to the problem solving of material modeling of mechanics.
  2. Endeavors to the precise and error-free problem solving for material modeling.
