Brass Tension Test

Our ME395 lab preformed a tensile test in order to measure Young's modulus for a naval brass specimen.

This video shows the necking stage of plastic deformation and the eventual failure of the brass piece.

physics is just a codename to play with cool toys

[mightyboybrian]

I second that

[wagoneers]

awesome

What can I say? my life is sweet.

That's a cool fracture surface. While some ductile fracture surfaces have a nice axial symmetry to them, with a fairly flat crack on the outside, this seems to have some clear indications of shear failure (failed at max shear, 45 degree lines)

I could be wrong, though.

[supercharge09]

that's just brittle.

Seconded.

Ductile materials have a plastic region (or permanent deformation.)

Brittle materials fail at yield.

[jambourijunkie3000]

actually, the yield is before the necking, its the point at which the material first "gives in" to the stress, stretching out permanently. its not until a considerable further load is applied that it reaches the point where necking, and complete failure happens

i think there is no any yeld zone very ductile small diametre before made a necking.

my comment : test is not pass.

[lagphish]

nice fracture surface - very ductile
