OBJECTIVES
The students are introduced to various methods of analysis and evaluation of
mechanical properties in terms of stress, strain and deformation in different loading
modes: tension, compression, shear and torsion. This knowledge is essential for
25
understanding mechanical behaviour of materials. Testing of materials for determination
of properties is dealt with in detail.
UNIT I STRESS STRAIN AND DEFORMATION OF SOLIDS 9
Rigid and deformable bodies – Strength, Stiffness and Stability – stresses; tensile,
compressive and shear – deformation of simple and compound bars under axial load –
thermal stress – elastic constants – strain energy and unit strain energy – Strain energy
in uniaxial loads.
UNIT II BEAMS - LOADS AND STRESSES 9
Types of beams: supports and loads – shear force and bending moment in beams –
cantilever, simply supported and overhanging beams – stresses in beams – theory of
simple bending – stress variation along the length and in the beam section.
Elastic curve of neutral axis of the beam under normal loads – Evaluation of beam
deflection and slope: Double integration method, Macaulay Method, and Moment-area
method – Columns – End conditions – Equivalent length of a column – Euler equation –
Slenderness ratio – Rankine formula for columns
UNIT III TENSILE TESTING 10
Engineering stress and engineering strain curve, true stress and true strain curve,
instability in tension, effect of strain rate and temperature on flow properties, tensile
specimens and testing machines. Notch tensile test, anisotropy of tensile properties.
UNIT IV HARDNESS TESTING AND IMPACT TESTING 9
Brinell, Vickers, Rockwell, Rockwell superficial, rebound, micro hardness tests and
testing machines. hardness conversion. Impact, IZOD, Charpy, Instrumented Impact,
relation to KIC
UNIT V TORSION AND TORSION TESTING 8
Analysis of torsion of circular bars – Shear stress distribution – Bars of solid and hollow
circular section – Stepped shaft – Twist and torsion stiffness – Compound shafts – Fixed
and simply supported shafts – Application to close-coiled helical springs – Maximum
shear stress in spring section including Wahl Factor – Deflection of helical coil springs
under axial loads – Design of helical coil springs – stresses in helical coil springs under
torsion loads
