Strain vs displacement

Submitted by Anonymous (not verified) on

Hi,

in a clamped bar at one end submitted to tension at the other end, the deformation, as well as stress, is constant while the displacement is linear.So, at the clamped end displacement is null wheras deformation is constant! could anyone explain me this paradoxe?

Thanks a lot. 

We have this formula for DeltaX=Px/AE

Which is linear deformation for a bar subjected to a axial

load P.

X is the distance from clamp side to the place you are measuring

the deformation. And A is the cross sectional area , E is young modulus.

So right on the clamp point DeltaX=0
