Hi all
I was wondering if someone could help explain what the area under a load vs deflection curve tells you.
I have a concrete sample which I loaded until it failed.
I plotted the load (kN) and deflection (mm) as shown below.
My question is; if the curve in red can be represented as a function f(x) (which I can do via regression) and I integrated this function from 0 to 0.75 (0.75 was the deflection at failure) then what does this tell me?
What does the area under the curve tell you?
From my research the area under a load vs deflection curve is meant to represent energy absorption but others have said it actually represents Work done?
I was wondering if someone could explain?
Thank you.
