PHYSICAL PROPERTIES OF MATERIAL

STRENGHT: Ablity of materials to resist deformation

ULTIMATE TENSILE STRENGHT; Maximum resistance to fracture

YEILD STRENGHT; Stress at which perdetermined amount of permanent deformation

MALLEABILITY; Percentage enlongation reported in a tensile test.
is also define as maximum enlongation of the guage lenght divided by the orignal guage last.
Ability of material to enlonged in tension.
DUCTILITY; Ability of material to deform easily upon the application of a tensile force

TOUGHNESS; Is describe the way a material reacts under sudden impacts

HARDNESS; Property that enable materials to resist plastics deformation penetration indentation and scratching.
