 THE SHARD file:///C:/Users/Alumne/Downloads/THE%20SHARD%20(2).pdf

HARDNESS: Property of material by which they are diffficult to compress or scratch is called hardness. For example, iron and copper are hard materials . VIDEO:

  ELLASTICITY : Property that bodies have of changing their shape when an adequate force is applied to them and of recovering their original shape when the action of the force is suspended. Elasticity has a limit, if it is exceeded the body suffers permanent deformation or breaks.

  TENACITY :Tenacity is a force that drives with determination, and without giving up on something you want to do or archieve. MATERIALS: iron, wood

PLASTICITY - DUCTILITY -MALLEABILITY PLASTICITY : Is a mechanical behavior characteristic of certain anelastic materials consisting of the capacity to deform permanently and irreversibly when subjected to stresses above their elastic range, above their elastic limit   DUCTILITY: Is the property that some metals and allies ha ve, when under the action of a force, they can be stretched without being twisted (metal sheets) MALLEABILITY: The ability to be easily changed into a new shape (metal threads) One example of sustainable material is steel. One 96% of the steel is recyclable and it’s a very useful material and obviously it’s a material with lots of plasticity   

 STRENGTH: The ability of a material to resist mechanical forces when in use.
