Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied. 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.

Objects around us are made up of different materials. Different materials may have similar or different properties. One property of materials is hardness. Ha

As the hardest tissue in the human body, enamel is not an easy material for engineers to mimic, but doing so could mean big things in materials science and regenerative medicine. Researchers are

Hardness is a metric that measures how resistant a material is to localised plastic deformation caused by mechanical indentation or abrasion. It has important diagnostic properties in mineral identification or abrasion. There is a general bounding between hardness and chemical composition, thus most hydrous minerals like halides, carbonates, sulfates, and phosphates

Hardness is a material's quality to withstand localised deformation. It may be especially important when looking for a suitable material for 

hard•ness (ˈhɑrd nɪs) n. 1. the state or quality of being hard. 2. that quality in water that is imparted by the presence of dissolved salts, esp. calcium sulfate or bicarbonate. 3. the comparative ability of a substance to scratch or be scratched by another. 4. the measured resistance of a metal to indention, abrasion, deformation, or machining.

Hardness is the resistance of a material to localised plastic deformation. Hardness ranges from super hard materials such as diamond, boron-carbide to other ceramics and hard metals to soft metals and down to plastics and soft tissues.
