DISCUSSION OF HOMEWORK

STRAIN GAGES / LOAD CELLS

THREE MAJOR CLASSES OF MATERIALS

          METALS
          CERAMIC
          POLYMERIC

FOUR TYPES OF ATOMIC BONDING

         IONIC
         COVALENT
         METALLIC
         VAN DER WAALS FORCES

METALS - BASIC  (UNIT CELL) TYPES

         BCC
         FCC
         HCP

CRYSTALLINE GROWTH

         NUCLEATION
         CRYSTALS
         GRAINS
         BOUNDARIES

         IMPERFECTIONS
                Dislocations
                Vacancies
                Impurities
                Inclusions
                Interstitial

MATERIAL PROPERTIES DEPEND ON
         Crystal lattice
         Grain distortion by boundaries.
         Grain size is affected by temperature
         Nature of Materials
             allotropic change of some materials
             Iron (the base element in steel)

DEFORMATION:  PLASTIC  &  ELASTIC

         ELASTIC - (lattice structure is distorted but reorients)
         PLASTIC (occurs by slip along lattice, atomic bonds are broken)
                Hardening may occur during plastic deformation
                           Results from entanglement of dislocations and grain boundaries
                           Can be eliminated by recrystallization at elevated temperatures.
