“…Zhang et al [12] studied, inter alia, the impact of grease and the clearance between the punch and die block on the press formability of AZ31 alloy. Chang et al [13] conducted simulations using the finite element method for warm forming process of AZ31 alloy drawpieces and obtained compliance with the results of experimental studies. Similar studies were conducted by Lee et al [14].…”

The purpose of warm forming is to reduce the deformation resistance, and therefore the formation of products at reduced pressures. A key problem associated with warm sheet metal forming is uniform heating of the material to a required temperature. This task is carried out mostly by using resistance heating plates. The article presents the results of the analysis of the thermal state of a heating plate for induction heating of an AMS 5604 stainless steel sheet. To determine the temperature distribution on the sheet surface an FLIR P 640 thermal imaging camera was used. It was found that the temperature difference on the outer surface of sheets preheated to the temperature of 900°C was about 300°C. A large difference in the temperature on the outer surface of the sheet means that the analysed device cannot be successfully used in the heating process of stainless steel sheets. After the application of a layer of graphite on the sheet surface to increase the emissivity, areas of low emissivity as a result of graphite detachment from the sheet surface were observed.

Chang i inni [16] przeprowadzali symulacje z wykorzystaniem metody elementów skończonych procesu kształtowania na półgorąco wytłoczek ze stopu AZ31 i otrzymali zgodność z wynikami badań eksperymentalnych. Podobne badania przeprowadzili Lee i inni [17].…”

MECHANIK NR 3/2015 ___________________________________________________________ 341Celem badań eksperymentalnych było określenie właściwości mechanicznych blachy nierdzewnej AMS5604 w temperaturze otoczenia (20°C) oraz w temperaturze podwyższonej w zakresie 50÷800 °C. Wyznaczono rów-nież wpływ prędkości odkształcenia na zmianę wartości podstawowych parametrów mechanicznych blachy. Próby statyczne rozciągania przeprowadzono w Laboratorium Badań Materiałów dla Przemysłu Lotniczego na maszynie wytrzymałościowej Instron 5982 (100kN). MECHANICAL PROPERTIES OF AMS5604 STAINLESS STEEL SHEETS AT ELEVATED TEMPERATUREThe aim of the experimental studies was to determine the mechanical properties of stainless steel AMS5604 at ambient and elevated temperature in the range of 50÷800 °C. The effect of strain rate on the change in the value of basic mechanical parameters of the sheet metal is also determined. The static tensile test is carried out at Research and Development Laboratory for Aerospace Materials using Instron 5982 100KN floor model universal testing system.

“…Penetration of the occurred crinkle into the gap between the stamp and the die may result in jamming of the draw piece, rupture of the base, or cracking of the die wall. The limitations causing draw piece or tool damage are described by the researchers in publications [1,3]. The corrugation phenomenon occurs mostly during the shaping of axially-symmetrical draw pieces.…”

The subject of the study was aluminum samples of varying thickness. The aim of the study was to perform the experimental stamping process of the samples on a universal testing machine and a numerical analysis on two independent computer systems Abaqus® and Deform-3D. As part of the numerical analysis, bilinear material model was included, taking into account elastic and plastic characteristics. The study was conducted in a dynamic environment with geometric nonlinearity. The results obtained from experimental research were confronted with those obtained by FEM computer simulation. During the research, numerical model of the stamping process has been developed, which was validated with the results of experimental research.
