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. Split Hopkinson Pressure Bar Test is often used for these experiments. The 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 DC 01 steel too.
Czech abstract
Plastická deformace kovových materiálu a slitin je komplexní proces, který závisí na mnoha faktorech ovlivňující rychlost deformace. Dynamické zkoušky jsou používány pro popis mechanických vlastností. Zařízení Hopkinsonovy dělené tyče (SHPBT) je často využíváno k těmto účelům. Článek se zabývá možnostmi, jak testovat ploché vzorky na tomto zařízení. Cíl této práce je zaměřen na vliv rychlosti deformace u oceli DC 01.
