opposite are two sample geometries used in the tensile testing of metals.
The wide ends of these are held in the sample grips of the testing machine.
The narrower central region experiences the highest stress values and the
mechanical deformation takes place in this region.
Flat test sample geometries are good for evaluating materials to be used in plate form, the round sample geometry is used for the same materials if they are to be used as extruded bars, forgings, or castings. |
