Ductile material reauires more energy then brittle material to fracture.....But in the stress strain curve you told that brittle material requires more stress for fracture...than how both statement is justify
Great question. The answer is simple though; you need to understand the difference between 'stress for fracture' and 'energy for fracture'. Stress for fracture is the stress value (load/area) at which the material fractures whereas energy for fracture is the total energy absorbed by the material before fracture and this is given by the area under the stress strain curve. So if you observe the stress-strain curve of a ductile and a brittle material to observe the difference. For a brittle material the stress value for failure is high but the area under the curve is less. Whereas for a ductile material the stress value for fracture is low compared to brittle material but the area under the stress-strain curve (energy) till fracture is much greater. Hope this clarifies your confusion. In case something still isn't clear, do drop a message and I will explain it again
The potential energy required to breaking the bonds (bond energy) is the area under the stress- strain curve. i.e Toughness and resilience. At least that is what I think.
Thanks a lot Pragya Rathor. Due to some unavoidable reasons we are unable to upload videos for now, but we hope to resume video making soon. Hopefully, we will do more videos on engineering and shall keep in mind the topics suggested by you. In the meantime you can watch our other videos from the collection of over 5000 videos.

it is nice lecture keep up it
At 8:32 when you describe the ductile fracture mechanics the red box reads "small micro words", but I think you meant "small micro voids"
