Test data compression is one of the main objectives to make reliable in testing System on chip design. The data compression mainly relies in the areas of hardware, time and power consumed. This paper presents an efficient test data compression method to achieve high compression ratio. The test patterns have 1, 0 and undefined (x) data. The test patterns are grouped such that to improve compress...

Flexible Polyurethane (PU) foam samples with different densities and chemical formulations were tested in quasi-static stress-strain compression tests. The compression tests were performed using the Lloyd LR5K Plus instrument at fixed compression strain rate of 0.033 s-1 and samples were compressed up to 70% compression strains. All foam samples were tested in the foam rise direction and their ...

Abstract This paper presents experimental results and finite element analysis of hot upsetting titanium alloys Ti64 Ti407 using a dilatometer in loading mode. All samples showed barrelling, as consequence an inhomogeneous temperature distribution friction. The FE is full thermomechanical model the test calibrated multiple thermocouples. At each nominal strain rate, true flow stress–strain respo...
