Hardness Hardness Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. Some materials (e.g. metals) are harder than others (e.g. plastics, wood). Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness: "scratch hardness", "indentation hardness", and "rebound hardness". Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and superhard materials, which can be contrasted with soft matter. There are three
Janka-Puszta this way the camp fell into disuse in late 1934. Janka-Puszta Janka-Puszta or Jankovac was a training camp set up for the Ustashe terrorist organisation in 1931. The camp was located in the Zala County of Hungary, close to the border of the then Kingdom of Yugoslavia near the villages of Murakeresztúr and Belezna. The camp was one of a string of training camps established in Hungary and Italy by the Ustashe. It housed several hundred émigré recruits, mostly manual laborers returning from Western Europe and North America. The recruits swore an oath of loyalty to the leader of the
