·
The
Impact testing apparatus shown permits the energy absorbed in a high strain-rate
fracture of a material to be measured. The notched
samples shown localize the maximum stress in the notch region.
· The
energy absorbed is computed from the difference in height between the pre-
and post-impact positions of the pendulum.
· Measurements
may be made at different temperatures to explore the ductile to brittle
transition behavior of the material. |
