contents 13 Tom McGaughy and Fabian Orth Several subtle factors related to specimen geometry and microstructure are not fully addressed in most test standards, even though they may affect fracture toughness values. ON THE COVER: A 100 kN materials test machine operating in concert with an industrial robot in an automated testing system. The robot is loading a metal test specimen for a tensile test, during which a laser extensometer will measure elongation for complex strain analysis.
