Instrumentation for Fracture Toughness Evaluation with Charpy Impact Specimen.

Abstract

An instrumented impact test system comprised of analog circuits was designed, assembled and tested. The system is capable of furnishing a digital display of static and dynamic fracture toughness, impact energy and time to fracture along with a hard copy print-out and oscilloscope presentation of the forcetime trace. The computation circuits are described along with operation procedures and principal logic inputs. (Author)
