Introduction Flashcards
Main properties of material (6)
Stiff, strong, ductile, tough, brittle, hard
Define Young’s (Elastic) Modulus
Value that measures a material’s resistance to being deformed elastically (How stiff is a material)
Define toughess of material
Material can take a lot of energy without breaking
Define ductility of material
Material Deforms under pressure
Define brittle in material
Material that breaks with little deformation
Define hardness in material
How hard a material is to dent, scratch, and wear
Define yield strength in material
How much stress a material can take without deforming plastically
Define ultimate strength in material
How much stress a material can take without breaking
Categories of properties (6)
mechanical, electrical, thermal, magnetic, optical, and deteriorative
Describe the relationship among the four main components of materials
Processing -> Structure -> Properties -> Performance
Basic classifications of solid materials:
metals, ceramic polimers, and composites
Main physical properties of metals:
stiff, strong, ductile, resistant to fracture
Main physical properties of ceramics.
stiff, strong, hard, brittle
Main physical properties of polymers:
low density, neither stiff nor strong
What is the main purpose of composites
Can be designed for anything
