TL;DR: In this article, the authors describe a dynamic indentation (DI) technique suitable for the determination of the high strain rate flow behavior of ductile metals and alloys and illustrate its use by characterizing the high-strain rate flow behaviour of iron and OFHC copper.

TL;DR: In this article, the authors evaluated the constraint factor associated with the indentation process as a function of strain in the case of metallic materials exhibiting a wide range with respect to elastic modulus, strength, and strain-hardening rate.

TL;DR: In this article, the nature of the elastic rebound of a tungsten carbide ball when it is impacted against metallic target materials having a wide range with respect to hardness and elastic modulus was characterized.

TL;DR: In this paper, the response of four metallic materials indented under both static and dynamic indentation conditions using spherical balls has been compared, in particular, the hardness-average strain behaviour, the shape and extent of lip formation around the periphery of indentation and the size of the plastic zone formed around the indentation in the material being indented.

TL;DR: In this article, the authors describe the experimental procedure for obtaining stress-strain curves from hardness tests and the indentation test conditions under which the conversion of the hardness-average strain data to flow stressstrain data is simple and straightforward in the sense that the constraint factor which is the correlating parameter for the above conversion is not only independent of strain but also easily computable on the basis of known mechanical properties of the test material.
