Abstract
Recent developments in dynamic testing of materials
Highlights
Numerical simulation of the response of materials to loads has reached a level of maturity at which it can be used with confidence for design
The second experimental technique that is under development is a dynamic tension experiment in which full-field strain measurement with Digital Image Correlation (DIC) and full-field temperature measurement are done simultaneously during the test
Numerical codes like LS-DYNA and Abaqus include many material models for plastic deformation and failure that can be selected for specific applications
Summary
Numerical simulation of the response of materials to loads has reached a level of maturity at which it can be used with confidence for design. Numerical codes like LS-DYNA and Abaqus include many material models for plastic deformation and failure (constitutive relations) that can be selected for specific applications. The various models require input parameters that are specific to the material that is being simulated. Accurate experimental results from tests under well-controlled conditions are needed for the determinations of the parameters in the material models as well as for the validation. The current paper presents two new testing configurations that have been developed recently for the purpose of providing fundamental data for determining the parameters in material models for dynamic plastic deformation and failure. Results from testing Inconel 718 over a wide range of strain rates and temperatures are presented
