Stress Strain Curve | Full Explanation by Ashish Ranjan, ex-ISRO, ex-BARC Scientist

Ashish Ranjan, a Mechanical Engineer with a background as a Scientist at ISRO and BARC, specializes in fluid flow analysis and thermal design of propulsion systems. He is also the author of the fiction novel "The Boy Who Did Not Sign."

One of the most frequently asked questions in Mechanical, Civil, and Aerospace Engineering interviews is about the stress-strain curve. Many graduates lack a comprehensive understanding of this crucial concept, including its details, significance, and physical interpretation. This video aims to clarify the stress-strain curves for Mild Steel, Aluminium, and Cast Iron. We will cover essential points such as:
• Elastic Limit
• Proportionality Limit
• Upper Yield Point
• Lower Yield Point
• Ultimate Tensile Strength
• Fracture Point
Additionally, we will discuss critical concepts for engineering understanding and interviews, including Hooke's Law and Proof Strength.

[YOUTHICON]

The best valueable YouTube channel I find in my entire life. ❤

[aryanpatel]

THE WAY YOU COVERED EACH AND EVERY MINUTE DETAILS AND CONCEPT RELATED TO STRESS STRAIN CURVE IS AMAZING THANK U VERY MUCH FOR THIS INITIATIVE

[uksachin]

Now I am Getting The points. This Level Of conceptual clarity was the Reason by which you were able to crack the high level exam .
Respect Bhaiya

[hemanth]

Sir, please continue these type of vedios.
It will be useful for interview preparation.

[shanuvashisth]

Hi bhaiya, I am also a mechanical engineering student, loved this video. Please bring the next video of Iron Carbon Phase diagram and TTT curve.

[Pavankalyan-ycid]

Please make more of these videos since we people have npcil interviews.
Your explanations may really help us.

[Patriotic_Hindu]

Please keep posting these small yet important concepts in different videos, YouTube blessed me with this one. Algorithm is doing it's job well 😄😁

[shubhamrana]

Not from an engineering background but still watching the video.

[Komal_Kay]

Just the right video I needed. Huh! That's what keeping you busy throughout the day lol

[bruh____]

I definitely think youre gonna become the next great innovator. Love your work brother

[radhakrishnanmanickavasaga]

Thanks ashish bro
I never understood principle stress

[tanmayrohit]

Much needed refresher!, Please also cover Principal Stress and Theory of failures criteria's

[syedsuhailahmed]

Awesome Explanation. PLEASE MAKE VIDEO LIKE THIS.

[shindesarkar]

Your Som, MD, Thermodynamics and hydraulic machine unacadamy course doesn't exist 😢😢😢 please check

[kashishgarg]

Hii, it's really an amazing explanation of all the points on the graph (also with the examples of materials and thier stess values at different points).
You said that we will be gonaa discuss about that dip (after elastic proportional limit, which you have also named but I don't remember it now😅).. so kindly discuss about that point and also please make an complete video which includes the complete knowledge of these important graphs and topics (with the examples of your research based knowledge so that we can have a clear cut knowledge about that and don't have to spend the months in searching for these valuable information in books)..


Hope you will stay fine and healthy.
Keep us with you in your journey

Hey Ashish, I've got a question unrelated to this video. I'm 18, about to turn 19 soon, and I've failed the JEE once again. I recognize my mistakes; I didn't manage my resources properly and didn't heed my teachers' advice. I pursued my own path without much direction, and now I'm facing the consequences. I've invested three years into this exam, only to find myself in a miserable state. I tied my self-worth to those three letters, "IIT, " and now that dream feels completely shattered. You weren't an IITian, yet you worked hard and overcame your struggles. Can I ever shake off this guilt and regain my confidence? Getting into an IIT as an undergrad was my goal, and failing to achieve it leaves me uncertain about my future. Even if I qualify for the GATE exam through hard work, I wonder if it'll ever fill this void. I believe you can offer some guidance. Thanks. <3

[deez_nats]

Really had some positive changes in my life after watching your videos

[Adityasinghmv]

Bhai aise bahot saare videos banaiye please

[himanshu.youtube]

11:04 You showed the true stress curve deviating from engg stress curve from the point of ultimate tensile strength but the chnage in are of mild steel rod can be significantly seen after the lower yield point . Why not deviate true stress curve from the lower yield point ??

Help me with my confusion.😊

[arnablahiri]

suppose instead of giving tensile load, you give compressive load to mild steel, will that make any difference in stress versus strain curve?
