1. Hardness

   In materials science, hardness (antonym: softness) is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. In general, different materials differ in their hardness; for example hard metals such as titanium and beryllium are harder than soft metals such as sodium and metallic tin, or wood and common plastics. Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, hardness can be measured in different ways, such as 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.

1. hardness

   Hardness refers to the resistance of a material to deformation, indentation, penetration, scratching, or bending. It is often measured by the extent to which a material can withstand friction or wear. The level of hardness is usually determined by various tests such as Brinell, Vickers, or Rockwell hardness tests. It is an important determinant of a material's durability and strength.

Examples of hardness in a Sentence

1. Barbara Paley:

5. R. Buckminster Fuller:

   Children are born true scientists. They spontaneously experiment and experience and reexperience again. They select, combine, and test, seeking to find order in their experiences - "which is the mostest? which is the leastest?" They smell, taste, bite, and touch-test for hardness, softness, springiness, roughness, smoothness, coldness, warmness: the heft, shake, punch, squeeze, push, crush, rub, and try to pull things apart.
