The use of surface appearance in combination with charpy impact energy to determine J-integral values
conference paper
This paper gives the theoretical basis for a new method of
using Charpy data to estimate fracture toughness in the
transition region by using both fracture surface appearance and
the traditional Charpy energy. Prior research has shown that the
Charpy energy and fracture surface appearance can be used to
estimate the upper-shelf J-integral [1]. The current paper
extends those ideas by using that same information not to
estimate upper-shelf Charpy energy, but to estimate the
toughness of fracture mechanics specimens at the same
temperature
