## Concurrent to experimental evidences that display certain correlation between ultrasonic (attenuation and velocity) factors and fracture toughness, there have been findings of certain correlation between fracture toughness and material microstructures. In an attempt to provide a mechanics view

## Abstract Few engineering materials are limited by their strength; rather they are limited by their resistance to fracture or fracture toughness. It is not by accident that most critical structures, such as bridges, ships, nuclear pressure vessels and so forth, are manufactured from materials tha
A general defioition of fracture toughness, designated by 6, is developed which is appropriate to situations of subcritical crack growth and/or kvge-scalc crack border plastic yield. The theoretical basis as well as comparisons with other proposed measures of fracture toughness are also discussed. A
