FORMING ANALYSIS OF CONTINUOSLY ANNEALED, DOUBLE REDUCED STEEL SHEETS

摘要

The paper deals with the forming analysis of continuously annealed steel sheets double reduced. Six different sheet metal grades were evaluated in the paper, thickness was in the range from 0.15 to 0.175 mm. Described are the used methods and the results obtained by a uniaxial tensile test, biaxial test (bulge test) and a springback test. Results should lead to the optimization of the test method for determining the objective mechanical properties of the sheets and thus to create the conditions for their trouble-free processing by drawing.
