After the course, student knows how to model structures as collections of solid, plate, beam and rigid parts and determine (1) small displacements of structure, (2) small displacements as function of time and vibration properties of structures, (3) stability properties and critical load of beam and plate structures, (4) displacements of bar, thin slab, and solid parts according to large displacement theory, and (5) temperature and displacements of structure simultaneously using thermo-mechanical analysis.-
TEACHING
Responsible teacher: Jouni Freund (JF)
Teacher: Markku Malmivuori (MM)
Lectures on Tue (14:15-16:00) and Wed (14:15-16:00) are based on the lecture notes available in the homepage on Fri of the previous week. Lectures are recorded.
Exercise session on Thu (12:15-14:00) is a lecture on solving the weekly exercise problems by hand, with MathType, and FE-code of the course. Exercise sessions are recorded.
Calculation hours on Thu (14:15-16:00) is an informal meeting for instructions, discussion, and questions on the weekly assignments. Calculation hours are not recorded.
COURSE MATERIAL
Course material of weeks 2-7 is published in the home page on Fri of the previous week.
Lecture notes of weeks 2-7 for the Mon and Tue lectures contain the theory and examples related with the weekly topic.
Example problems of weeks 3-7 contain answers and full solutions. Some of the hand-calculation and/or Mathematica solutions are explained in detail during the Calculation examples lecture on Thu.
Lecture assignments (1,2) of weeks 2-7 are discussed during the last 30min of the lectures and later on the same day during the Calculation hours session. The dead-line is the day of discussion and calculation hour 23:55.
Home assignments (3,4,5) of weeks 2-7 are discussed during the Calculation examples lecture and Calculation hours on Thu. Some of the problems are structured and contain templates to be completed, some are non-structured to be solved from scratch. The dead-line is Sun 23:55.
All assignments are published and available in doc and pdf versions in the home page only. With the doc version, you may use MathType equation editor to fill the missing parts of a structured assignment or write the full solution to a non-structured assignment. Return of the solution through MyCourses should be pdf in type. Also handwriting with a paper printout (with pdf conversion in some manner) is accepted if the quality is good enough.
COURSE SOFTWARE
Calculation hours on Tue and Wed use Zoom:
https://www.aalto.fi/en/services/zoom-quick-guide
Assignments of the course are published and returned through MyCourses. Be prepared to use an equation editor and a tool for pdf-conversion:
https://download.aalto.fi/index-en.html
FEM solver of the course requires Mathematica software to work. Download Mathematica in good time (it may take a few days to get the license)

FINAL EXAM (OPTIONS)
Onsite exam (in Otaniemi campus) consists of five (5) problems from the set of solved example problems of the course material. In the onsite exam, you may use only the formula collection of the course. The time for the exam is 4h.
Online exam consist of four (4) problems published and returned through MyCourses in the same manner as the assignments of the course. The problems are not as “technical” ones as those of the onsite exam and they might also require a bit modelling. The time for the exam is 4h. In the online exam, you may use any material. However, you are supposed to solve the problems by yourself.
Solutions to the modelling assignment, home assignments, and lecture assignments are graded so that the maximal points correspond to one correctly solved exam problem in the final grading of the course. Participation in the final exam is possible only if the points from the assignments exceed half of the maximal points.
You may participate either the online or onsite exam. However, after passing the course, improving the grade is possible only in the onsite exam!
-
Formula collection of the course (pdf and docx)
List of elements and operations of Mathematica FE-code (pdf).
-
The FE-code (file) of the course is updated weekly with solutions to examples in lecture notes, exercise problems of the week, and assignments of the week. You can use the code, e.g., to check the outcome of hand calculations. To access the code:
1. Download the Mathematica software.
2. Download and save the file "Fem MEC-E8001" (Mathematica solutions).
3. Click on the "Fem MEC-E8001" icon to start Mathematica.
4. Open and evaluate "shift-enter" the cell for a problem to see a Mathematica solution.
