intro

Question 1

structural materials important characteristics

Answer 1

streght, toughness, density, wear resistance, corrosion behaviour…

Question 2

functional materials characteristics

Answer 2

used for their specific funtionalities as:
-magnetism, electrical or thermal conductivity, thermal expansion, damping
-porosity, architectural shape, anisotropy
-interaction and reaction with environment

Question 3

smart materials characteristics

Answer 3

step further than functional materials.
they can react to external stimuli by providing a change in their behaviour or properties
(stimuli as: temperature, mechanical stress/strain, temperature, electric/magnetic flow, light)
