Topic outline
-
After the course: (1) Student knows the ‘divide-and-rule’ engineering paradigm for structure modelling, (2) is able to model structures as collections of solid, plate, beam and rigid parts, (3) knows the principles and concepts of FEM, (4) is able to derive element contributions of solid, plate, beam and of rigid elements, and (5) analyze simple structures and machine parts by hand calculation and the FEM software of the course.-
COURSE SOFTWARE
Lectures of the online course use Zoom:

TEACHING
Lectures on Mon (10:15-11:30) and Tue (14:15-15:30) are based on the lecture notes available in the homepage on Fri of the previous week. Lectures of weeks 45-49 are followed by lecture assignments to be returned during the same day.
Exercise session on Thu (14:15-15:30) used for calculations examples by hand and FE-code of the course.
Calculation hours 10:15-12:00 on Fri is an informal meeting for instructions, discussion, and questions on the weekly assignments.
WEEKLY COURSE MATERIAL
Lecture notes (weeks 44-49) are published in the home page on Fri of the previous week. The notes for the Mon and Tue lectures contain the theory and examples related with the weekly topic.
Modelling assignment (week 44) is published in the home page on Fri of week 43 and should be returned through the homepage before Sun 23:55 of week 44.
Exercise problems (weeks 45-49) are published in the home page on Fri of the previous week. Exercise problems contain answers and full solutions. Some of the hand-calculation and/or Mathematica solutions are explained during the Exercise session on Thu and Calculation hours on Fri.
Lecture assignments (weeks 45-49) are published in the homepage after the lectures on Mon and Tue and should be returned during the same day 23:55 at the latest.
Home assignments (weeks 45-49) are published in the homepage on Fri of the previous week and should be returned through the homepage before Sun 23:55 of the next week. Some of the problems are structured and contain templates to be completed, some are non-structured to be solved from scratch.
All assignments are published in doc and pdf versions. 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. Also handwriting is possible. Return of the solution through MyCourses should be pdf in type.
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 graded assignments exceed half of the maximal points.
FINAL EXAM (OPTIONS)
Onsite exam (in Otaniemi campus) consist of five (5) problems chosen from the set of solved example problems of the course material. In the controlled exam, you may use only the formulae 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 controlled exam but they might require also a bit modelling. The time for the exam is 4h. In the remote exam, you may use any material. However, you are supposed to solve the problems by yourself.
You may participate either the online or onsite exam. However, after passing the course, improving the grade is possible only in the onsite exam.
-
Formulae 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-E1050-2021" (Mathematica solutions).
3. Click on the "Fem MEC-E1050-2021" icon to start Mathematica.
4. Open and evaluate "shift-enter" the cell for a problem to see the Mathematica solution
