DESIGN OF EXPERIMENTAL TOOL FOR TUBE HYDROFORMING

Abstract

When forming a material, its good formability is essential. It is primarily influence by mechanical properties and chemical composition of the material. Formability can be assessed by mechanical tests, or technological tests. Tensile test is one of the most common mechanical tests used to obtain basic mechanical properties of the material. Another possibility how to evaluate the behavior of a material under given a load is to select a proper technological test with an appropriate experimental tool.  Design of a tool should be simple, save and it should allow monitoring during the test, i.e. tube hydroforming. Article deals with design of experimental tool for the realization of  experiments using radial hydroforming tubes whose ends will be fixed inside the tool because of an earlier setting of limit state of deformation.
