"Nah, I couldn't sleep, so I figured, I've never given you a fair shot at explaining what you're studying."
I was a bit suspicious.
"Sure, Mel, I've got a copy of my final paper for my Senior Design course here... We got an A!"
"I'll read a bit to you."
"In the linear elastic region the cell ligaments bend. As a stress is applied the ligaments bend linearly until the ligaments buckle and yield. This bending produces a linear curve whose slope is equal to Young�s modulus. If the stress is released prior to the yield stress the strain is recoverable and the material receives no net deformation. This is similar to a conventional engineering material.
Once the ligaments yield the plastic region begins. The plastic region consists of a nearly constant stress over a large strain. This is due to the plastic buckling of the ligaments. This �plateau� is ideal for absorbing energy..."
I looked back. Mel was fast asleep, with a little crooked smile on her face.
I get no respect whatsoever.
To tell you the truth though, it's a good thing she fell asleep, or I would have...
