Study Notes
### Material Properties
- Malleability: Ability to deform under compressive load without fracturing.
- Ultimate Tensile Strength: Maximum stress a material withstands before failing in tension.
- Resilience: Energy absorbed by a material under stress within its proportional limit.
- Viscosity: Resistance of a fluid to flow due to internal friction.
- Tensile Stress: Stress from two opposing forces in a straight line pulling the material apart.
- Hardness: Resistance of a material to indentation.
- Elastic Limit: Greatest stress a material can withstand without permanent deformation.
- Shear Stress: Stress that resists twisting or sliding of one part of a body over another.
- Cohesion: Attraction between similar atoms or molecules within a material
- Fatigue Strength: Stress at which a material fails under repeated loading within its elastic limit.
- Newtonian Fluid: A fluid with constant viscosity regardless of strain rate.
- Value: Lightness or darkness of a color in the Munsell system.
- Chemical Corrosion: Direct combination of metals and non-metals, often through oxidation.
- Elasticity: Ability of a material to deform under load and return to its original form.
- Metamerism: Appearance mismatch of color-matched objects under different light sources.
- Strain: Change in length per unit of original length (stretch) under load.
- Modulus of Elasticity: Ratio of stress to strain, representing material rigidity.
- Wetting: Ability of a liquid to spread on a solid surface (low contact angle suggests good wetting).
- Creep: Gradual deformation of a material under constant stress over time (especially relevant for low-melting point materials).
- Tarnish: Surface discoloration of a material due to environmental reactions.
- Proportional Limit: Stress at which the relationship between stress and strain becomes non-linear (no longer proportional).
- Vickers Hardness Test: Measures hardness using a pyramidal diamond indenter.
- Brittle Material: Fractures easily with minimal deformation.
- Electrochemical Corrosion: Corrosion process requiring an electrolyte (e.g., saliva).
