Study Notes
Material Properties & Dislocations
-
Yield strength is most sensitive to dislocation structures in materials.
- Dislocations are line defects in the crystal lattice that allow for plastic deformation under stress.
- The presence of dislocations reduces the stress required for plastic deformation, lowering the yield strength.
- Young's modulus, transparency, and conductivity are less sensitive to dislocation structures.
Biomaterials
- Biomaterials are materials designed to interact with biological systems.
- They can be natural or synthetic.
- Examples include polymers, ceramics, metals, and composites.
- Important aspects include:
- Biocompatibility: The material's ability to coexist with biological systems without causing adverse reactions.
- Bioactivity: The material's ability to elicit a specific biological response.
Biomedical Material
- Biomedical material is a broader category that encompasses materials used in medical devices and procedures.
- It includes biomaterials and other materials that are not necessarily designed for direct interaction with the body.
Biological Material
- Biological material refers to materials found in living organisms.
- Examples include bone, cartilage, and skin.
- They have unique structures and properties that make them suitable for their biological functions.
Normal Tissue
- Normal tissue refers to healthy tissues that are functioning properly.
- They have specific structures and functions that are vital for the body to thrive.
Wound
- A wound is an injury that damages tissue.
- Wounds can range in severity from minor cuts and abrasions to severe injuries involving major tissue damage.
- Wounds are often classified based on the nature of the injury, the depth, and the presence of foreign bodies.
Infected Wound
- An infected wound is a wound that has been contaminated with microorganisms.
- This contamination can lead to inflammation, pain, and potential complications.
- Different types of infections require different approaches to treatment.
