Abstract

This report presents the work done on Project 366, the Fracture Toughness of Structural Steels. The objectives of the program were 1) to conduct dynamic Kc type fracture tests on two structural steels across a range of plate thicknesses and temperatures, and 2) to explore plasticity concepts in formulating a fracture toughness characterization method in the range of general yielding where the linear elastic approach to fracture toughness evaluation is not possible.
