The paper presents experimental results of thermo-graphical measurement of material properties. The analytical expression for the temperature variation of the specimen deformed in the elastic state is determined starting from the first law of thermodynamics. The experimental method for determining material properties based on the Joule-Thompson effect is presented in detail. The thermo-graphical ...

The influence of strain paths (loading history) on material formability is well known in sheet forming processes. Sophisticated experimental methods are used to determine the entire shape of strain paths of forming limits for aluminum AA6016-T4 alloy. Forming limits for sheet metal in as-received condition as well ...
In the following paper, a full mechanical characterization of the AA6016 T4 aluminum alloy car body sheet DR100 is presented. A comprehensive experimental program was performed to identify and model the orthotopic elasto-plastic deformation behavior of the material and its fracture characteristics including ...
Sheet metal forming processes may often involve intense forming sequences, leading to large strains and severe strain-path changes. Optimizing such technologies requires a good understanding and description of the anisotropic plastic behaviour of the deformed material, in connection with the evolution of its texture and microstructure. In this paper, we present the predictions provided by a model ...

It is shown that increasing external field stimulates appearance of the conductive microplasma channels in a-As2Se3 thin films. Cooling a sample under high field causes the disabling of microplasmas and decreases the sample conductance by several orders of magnitude in a rather narrow temperature range. The diameter of a microplasma channel was estimated ...
