A linear elastic relationship, as described by Hooke's Law, is only applicable to normal stress and strain.
'n Lineêre elastiese verhouding, soos beskryf deur Hooke se Wet, is slegs van toepassing op normale spanning en vervorming.

Plastic deformation is related to slip due to shear stress along densely packed atomic planes; interatomic bonds are broken and atoms bond with a new set of nearest neighbours during plastic deformation.
Plastiese deformasie is verwant aan die glip wat veroorsaak is deur die skuifspanning langs die dig verpakte atomiese vlakke; interatomiese bindings word verbreek en atome bind met 'n nuwe stel naaste bure tydens plastiese vervorming.
Elastic deformation occurs when an applied load is sufficiently large enough to move atoms from their equilibrium spacing position in the crystal lattice without breaking any interatomic bonds.
Elastiese deformasie vind plaas as 'n aangewende las groot genoeg is om atome van hulle ekwilibriumspaseringposisie in die kristalrooster te beweeg, sonder om enige interatomiese bindings te breek.
While impurity atoms that are smaller than the host metal atom reduce the strength of the metal alloy, larger impurity atoms increase the lattice strain energy thereby increasing the strength of the metal alloy.
The approximate melting temperature of aluminium is 660 °C. The corresponding recrystallisation temperature for aluminium that has been cold-worked at least 5% is 80 °C. This correlates to the following relationship:
A steel rod is drawn from 10 mm to 7 mm diameter. It is then put through a recovery heat treatment during which the rod returns to its original diameter.
