ME 221 (S2)
Structural Materials
Autumn 2025
Course Objectives:
1. Understand the influence of composition, processing, and microstructure on mechanical
properties in structural materials.
2. Analyze atomic and microscale structures in solids and their impact on material behavior.
3. Explore experimental and computational advances in materials science for characterizing and
modeling material behavior.
4. Learn to apply this knowledge for part design, process selection, and final performance

Attendance Policy:
(Refer to UG rulebook)
IIT Bombay expects 100% attendance from its students in all classes.
Attendance will be collected in every lecture (within the first 5 min.) via the
SAFE app. Students with < 80% attendance rate (for any reason
whatsoever including medical grounds), will be imposed with up to 5%

penalty, leading to a potential reduction of 1-2 letter grades in their overall
performance.
To report ANY issue regarding the attendance, fill this form:
https://forms.office.com/r/cYk8r2Sgip (within a week after the event).
No need to approach TAs or send any emails.
Homework:
There will be several homework assignments throughout the semester,
typically via a set of questions at the end of every lecture. It is important to
note that these assignments will be for practice purposes and will not be
graded. However, it is highly encouraged for students to diligently complete
these assignments as they serve as essential preparation for the quizzes
and exams.
Quiz:
You will be given four pre-announced quizzes throughout the semester, and
the lowest quiz grade will be dropped. This will serve as 25% contingency for
any unforeseen emergencies including medical issues. No request for a requiz will be entertained for ANY reason whatsoever.
Tentative dates for the quizzes: TBA
The syllabus for each quiz will cover the material from the previous quiz up
to the lecture that occurs right before the quiz date.
Honor Code:
This class has a ZERO tolerance policy toward plagiarism. Any
student/group found to have committed or aided and abetted the offense
of plagiarism will receive ZERO marks for the relevant
assignment/quiz/exam/project without ANY exceptions.
