Evaluation of Standard Charpy Impact Properties with Subsized Specimens

Source

Evaluation methodology of standard Charpy impact properties in the cleavage fracture region from subsized specimen test results has been demonstrated. It consists of 1) subsized Charpy V-notch impact tests; 2) tensile tests at various temperatures and strain rates; and 3) three dimensional finite element method (FEM) simulations of the impact test with a temperature and strain rate dependent constitutive equation and a cleavage fracture model that is based on a stress-critical area criteria. The standard impact properties of a ferritic/martensitic steel (JFMS) in the cleavage facture region have been evaluated, and there was reasonable agreement between simulations and experimental results.
