Original abstract
Mechanical properties of forming steels (e.g.strength, deformation) change with the rare and time of contact between the piece being formed and the tool. One of the experimental methods that simulate real forming processes is Taylor anvil test. The present paper gives a comparison of deformation changes in test specimens stressed by impact force in dependence on impact velocity with structural changes in a selection of steels currently used in the manufacture of joining parts and mechanical engineering components. Comparing experimental results with the results obtained by the LS DYNA 3D simulation program performs the comparison of deformation changes in dependence on impact velocity.
Czech abstract
Mechanické vlastnosti tvařitelných ocelí (např. pevnost, deformace) se mění s rychlostí a dobou kontaktu tvářeného polotovaru s nástrojem. Jednou z experimentálních metod, které napodobují reálný tvářecí proces, je zkouška Taylorovým testem (Taylor Anvil Test). Tento článek popisuje srovnání změn deformace zkušebních vzorků namáhaných rázovou silou v závislosti na dopadové rychlosti a změně struktury u vybraných ocelí, které jsou běžně používány ve výrobě strojních a spojovacích dílců. Porovnání změn deformace na dopadové rychlosti je provedeno komparací výsledků experimentu a simulačního programu LS DYNA 3D.
