Study Notes
Mechanical, Physical, and Chemical Properties of Materials
- There are three principle types of stress: tensile, compressive, and shear stress.
- Mechanical properties include elastic limit, Young’s elastic modulus, fracture strength, yield stress, fracture toughness, ultimate tensile strength, ductility, resilience, and toughness.
- Mechanical tests include tensile, compression, hardness, impact, fatigue, creep tests.
- Rheological properties of materials include viscosity, thixotropy, and viscoelasticity.
- Thermal properties include thermal conductivity, specific heat, thermal diffusivity, and thermal expansion.
- Optical properties include color, translucency, and surface texture.
- Chemical properties are affected by the oral environment, leading to dissolution, corrosion, discoloration, and breakdown of materials.
- Polymers degrade due to water sorption, soluble fraction, and bond rupture.
- Ceramics are resistant to electrochemical corrosion but susceptible to chemical corrosion.
- Tarnish and corrosion of metals are two types of chemical degradation processes.
- Tarnish causes surface discoloration but does not deteriorate the material itself, while corrosion is a more serious chemical reaction between the material and its environment.
- Different types of corrosion include dry corrosion, wet corrosion, galvanic corrosion, and crevice corrosion, each with distinct characteristics and effects on materials.
