Introduction to Materials (Leaving Cert Engineering): Flashcards

Ability to resist scratching, indentation, or surface damage

They often become brittle and can shatter under impact

Ability to absorb impact energy without fracturing

Capacity to be stretched into wire shapes without breaking

Ability to return to original dimensions after force removed

Threshold beyond which permanent deformation occurs

Best cost-performance balance for conductivity

Temp where materials change from brittle to soft, flexible

Max pulling force before fracturing, measured in $\text{kN/mm}^2$

Ability to withstand repeated loading cycles over time

Ability to maintain shape under constant loading over time

Opposing forces creating a pulling effect on materials

Opposing forces creating a squeezing effect on materials

Combines both tension and compression simultaneously

Concrete with embedded steel rods or mesh
