Original abstract
Plastic deformation of metallic materials and alloys is a complex process that depends on a number of factors with the effect of strain rate being of particular importance. Dynamical tests are used for determination of mechanical properties. The Split Hopkinson Tensile Bar Test is often used for these experiments. The present paper deals with possibilities of testing device for flat bars adapted at Hopkinson test. The aim of this work is concentrated on strain rate influence on 1.4301 austenitic steel too.
Czech abstract
Plastická deformace kovových materiálů a slitin je složitý proces závislý na velkém počtu faktorů, z nichž zvláště významný je rychlost deformace. Pro dynamické zkoušky ke zjišťování mechanických vlastností kovových materiálů je běžně používán Hopkinsonův kompresní test. Tento příspěvek ukazuje na možnost adaptace zařízení Hopkinsonova testu pro tahové zkoušky plochých tyčí. V článku je mj. pojednáno o vlivu rychlosti deformace na austenitickou ocel 1.4301
