Determining Johnson-Cook Constitutive Equation for Low-Carbon Steel via Taylor Anvil Test ; Stanovení Johnson-Cookovy konstitutivní rovnice pro nízkouhlíkovou ocel pomocí Taylorovy kovadlinkové zkoušky
Abstract
Tristal steel is low-carbon construction-type steel widely used in the automotive industry, e.g., for braking components. Given the contemporary demands on the high-volume production of such components, these are typically fabricated using automatic sequential machines, which can produce components at strain rates up to 103 s1. For this reason, characterising the behaviour of the used material at high strain rates is of the utmost importance for successful industrial production. This study focuses on the characterisation of the behaviour of low-carbon steel via developing its material model using the Johnson-Cook constitutive equation. At first, the Taylor anvil test is performed. Subsequently, the acquired data together with the results of observations of structures and properties of the tested specimens are used to fill the necessary parameters into the equation. Finally, the developed equation is used to numerically simulate the Taylor anvil test and the predicted data is correlated with the experimentally acquired one. The results showed a satisfactory correlation of the experimental and predicted data; the deformed specimen region featured increased occurrence of dislocations, as well as higher hardness (its original value of 88 HV increased to more than 200 HV after testing), which corresponded to the predicted distributions of effective imposed strain and compressive stress. ; Tristalová ocel je nízkouhlíková konstrukční ocel široce používaná v automobilovém průmyslu, např. pro brzdové komponenty. Vzhledem k současným požadavkům na velkosériovou výrobu těchto součástí se tyto součásti obvykle vyrábějí na automatických sekvenčních strojích, které mohou vyrábět součásti při rychlostech deformace až 103 s-1. Z tohoto důvodu je charakterizace chování použitého materiálu při vysokých rychlostech deformace pro úspěšnou průmyslovou výrobu nesmírně důležitá. Tato studie se zaměřuje na charakterizaci chování nízkouhlíkové oceli prostřednictvím vývoje jejího materiálového modelu s využitím Johnsonovy-Cookovy ...
