Aerospace Materials Lab

This class is offered to the junior and senior aerospace engineering undergraduates at the UT Austin. It covers wide class of materials that include metal alloys, ceramics, and polymers. Students are trained on common testing methods and using the equipments used. Following video summarises one such test:

I’ve been a teaching assistant for this course for two and half years between Spring of 2023 and 2025. Following tables summarises the learnings from this experimental class:

Material Preprocessing Testing Methods Concepts Instruments
Steel Alloys Cold Working Uniaxial Tensile Testing Stiffness, Poissons Ratio, Stress-Strain Relationship and Regimes Instron
Aluminium Alloys Heat Treatments Uniaxial Tensile Testing Stress-strain relationship, Effects of various heat treatment Instron
Ceramics   Three point bending Stiffness Measurement, Probabilistic Model to account for Porosity Instron
Polymer (Polyethylene)   Uniaxial Tensile Testing, Stress Relaxation Test over various Temperature Creep, Relaxation, Viscoelasticity, Hysteresis Instron
Aluminium Alloy Fatigue Pre-crack Mode-I Fracture Fracture Toughness, Relation to plane-strain or plane-stress Instron
? Notched Charpy Impact Testing   Charpy Impact Test
?   Hardness Testing Hardness, Different Scales  
?   Fatigue Testing Fatigue RR Moore

The lab class usually starts with an brief overview of the theoretical background and testing methodology. This is followed by demonstration of material testing. The class proceeds in form of discussion. Question and answers are encouraged through the sessions.

High School Mathematics

During my secondary and high school, I was fortunate to have teachers who introduced mathematics in an interesting way. The riddles, finding better alternative solutions to same problems, staying on the problem, and building rigor in arguments are important traits. If not taught well it can turn someone who loves mathematics in school to hate it in undergraduate education as soon as they encounter the $\epsilon-\delta$ definition of limits, continuity, and derivatives. Thus, when an opportunity arose, I grabbed it to teach mathematics to high-school students. I was one of many teachers in the Nirmaan programme of my undergraduate institute.
