Instrumented end notched flexure - Crack propagation and process zonemonitoring Part II: Data reduction and experimental
PublicationA mode II instrumented end notched flexure three point bending (ENF) adhesion test is described. The adhesive joint consists of two aluminium alloy (AW7075-T6) plates bonded with a structural epoxy adhesive (Hysol EA 9395™). Strain gauges are attached to the outer surface (backface) of the substrates in the lengthwise direction to measure local surface strain during crack propagation. Simultaneously, load/displacement measurements...

The structure of electricity production in Poland (data as at the end of 2010)
Open Research DataThe energy market in Poland is characterized primarily by the use of only one raw material for the production of electricity. In 2010, as much as 91.4% of electricity was produced on the basis of hard coal or lignite. Therefore, the remaining sources used for the production of electricity participated in the production of electricity to a small extent....
