Autumn 2023
Prof. PJ Guruprasad
Author: Vighnesh J.R.
Pre-requisite courses: Nil
Pre-requisite skills: Linear Algebra, solid mechanics and structural mechanics, a bit of MATLAB
Course Content in Brief:
- The course extensively addresses numerical techniques for handling solid mechanics (and dynamics) and linear physical problems, encompassing heat conduction and viscous flow.
- We start with how to discretise domain into finite elements, connecting these elements, and deriving approximate solutions for differential equations.
- Emphasis is placed on solving the weak form of these equations hence employing energy-minimising like strategies to solve solid mechanics problems.
- The curriculum also focuses on understanding the physical significance of various kinds of boundary conditions and their practical implementation within FEM problems.
- Furthermore, students construct a 1D FEM Model applicable to simplified scenarios, such as analysing a tensile rod and a Euler-Bernoulli beam under various load.
- Following the mid-semester phase, participants are introduced to 2D FEM models for solving scalar and vector fields.
- We are also introduced to various elements and their corresponding shape functions.
- Finally the course is concluded by a brief overview of 3D FEM and numerical optimisation methods.
Motivation behind taking this course: A go to intro course for people interested in Linear Algebra and Numerical methods to solve solid mechanics problems. It is an engineering based course that gives good intuition to build up on the knowledge of the course provides. I took it because of its scope in combustion instability problems and also partly due to peer induced FOMO.
Info about Projects/Assignments: Prof gave a total of 6 assignments one of them was a coding assignment meanwhile the rest was problem sheets to be solved and uploaded online on moodle.
Evaluation Structure:
- 2 Quizzes (10% each)
- 6 Assignments (10%) (one is a coding assignment)
- Midsem (30%)
- Endsem (40%)
Attendance Policy: There is mandatory 85% but prof didn’t implement it properly due to logistics issues
Difficult level of Projects/Assignments: 2/5
Quizzes/midsem/endsem difficult level on a scale 1-5: 3/5
Level of effort you put into the course: 2/5
Feedback on Lectures (in terms of lecture delivery or ease of understanding, prof’s teaching style): Prof teaches in a medium-slow pace. He uses both slides and black board and he derives on board. He dedicates few lectures after teaching to problem solving. Unfortunately missed a lot of lectures when I took the course. Otherwise he could have covered a lot more.

General Fundae: It was a morning course. It’s relatively chill and he allows formula sheet for exams. Make sure to revise your jee integration skills and you have to use integration by parts too often.
Who can take this course?: Anyone interested in solid mechanics or heat flow or numerical methods in general.
