WitrynaTo convert J (energy) to J/cm 2 (specific energy), divide the energy absorbed by the area (in cm 2) of the un-notched ligament, i.e. by ( (W-0.2)xB)cm 2. For example, if the energy absorbed during testing of a full-size specimen is 100J, then the specific energy is 125J/cm 2. For a two-thirds-size specimen, an energy absorption of 100J would be ...
