The course, in short
Teacher
Djebar BAROUDI, Dr.
Main goals
• Understand the fundamentals of material modelling, i.e., constitutive equations, within the framework of continuum mechanics
• Comprehend underlying physics and related mathematical descriptions of key features of common material behavior (i.e., material models) in civil engineering related to their thermo-mechanical response
• Fully understand the material models used within commonly used computational tools in civil engineering with respect to thermo-mechanical behavior of solids
Content
The course is limited to
• ELASTICITY … linear, hyper-elasticity, non-linear, isotropy, transverse isotropy, anisotropy, orthotropy
• VISCOELASTICITY
• VISCOPLASTICITY …
• PLASTICITY ... associative, non-associative

About the course supporting Material
• In addition to the pointed chapters from the course textbooks for each topic, I will provide an additional learning/reading supporting material together with weekly homework series (3-6 exercises/week. Each exercise is marked (arvosana) 0-5 if not otherwise stated in the homework-paper).
• The Lecturer's written material is not a collection of lecture-slides but it is a learning supporting material offered to help and motivate students in their reading from the course textbooks & elsewhere.
• The topics treated in this intensive course cannot be avoided by future structural engineers: these topics will wait for them hidden, inside the FE-software you will use to perform structural analysis, in the black-boxes called material models. This course is may be the right place for first meeting them in a friendly learning environment and opening these black-boxes.
Passing the course
The individual written assignment (not to be confused with the 1st redaing assignment where the obligatory delivery is also a written report) is not compulsory. However, doing it makes you understand better and earn extra-points which may upgrade your exam grade.
15 points = 10 pnts referat + 5 pnts numerical example
