Fracture: Basic Concepts and Experimental Techniques
- 506 Downloads
The aim of this chapter was to define the basic concepts of fracture mechanics, and describe and discuss the basic phenomena that occur during fracture of materials. These concepts will be utilized in the next few chapters where we describe and discuss modeling of brittle fracture of heterogeneous materials and its transition to ductile behavior. We also described the experimental techniques that are used for measuring important characteristics of fracture of materials, such as the speed of crack propagation, and measurement and analysis of roughness of a fracture surface.
