Abstract
Fracture mechanics and finite element analysis are 20th-century technologies that have a profound impact on the way engineers design mechanical devices, structures, and material system. Although there is a wealth of literature in these two fields, the basic concepts of these technologies are simple. Fracture mechanics describes the transfer of mechanical energy toward the creation of crack surfaces. Finite element analysis is a numerical technique that solves continuum problems with an accuracy acceptable to engineers. Together these technologies provide powerful tools to predict critical loads or crack sizes that may cause fracture in proposed designs or existng structures. The U.S. Bureau of Mines is using such an approach to solve fracture problems in wear-resistant materials and to prevent premature rock failures in mining environments.
