Thank you NPTEL for making these lectures available for the entire international comunity! You are a shining example I hope many other educational facilities will follow.
sir explain the strain hardening in detail with relevance to stress-strain graph and a piece of advice that use some more descriptive slides with figures to make the lecture more connecting. thankyou for the effort you making sir really appreciate it
In stress-strain curve, u can see a rise in slope after plastic deformation, this is due to strain hardening.Basically what happens in strain hardening is the lattice gets disturbed(randomized) which makes the structure rigid,tighter. So it acts as resistance. So the material to fracture we need more stress to be applied. therefore we can see a rise in the curve
You people are simply great to post such valuble lectures.... One suggestion... it would be more helpful if you can show computer simulations or real time industrial videos... I think you can easily get them from companies...
