Original Abstract
Příspěvek popisuje využití Taylorova testu k zjišťování dynamických mechanických vlastností materiálů cestou simulace
English abstract
The paper focuses on the analysis of the Taylor test. One can say the method is very convenient for the study of material behaviour under impact loading conditions.There are simple analytic methods which enable to obtain a value of dynamic strength. The Taylor test results have been used to validate and obtain coefficients for empirical and semi-empirical stength models used for numerically simulating dynamic loading events. The optimizing procedure was used in order to obtained material constants of the johnson-Cook model.
