OBJECTIVE
To give brief
descriptions on the behaviour of materials due to axial, bending and torsional and combined
loads.
UNIT I
BASICS AND AXIAL LOADING 10+3
Stress and Strain - Hooke's Law -
Elastic constants and their relationship- Statically
determinate cases - statically
indeterminate cases -composite bar. Thermal Stresses -
stresses due to
freely falling weight.
UNIT II STRESSES IN BEAMS 10+3
Shear force and bending moment
diagrams for simply supported and cantilever beams-
Bending stresses
in straight beams-Shear stresses in bending of beams with rectangular, I
& T etc
cross sections-beams of uniform strength
UNIT III
DEFLECTION OF BEAMS 10+3
Double integration method - McCauley's
method - Area moment method - Conjugate
beam
method-Principle of super position-Castigliano's theorem and its apllication
UNIT IV TORSION 5+3
Torsion of circular shafts - shear
stresses and twist in solid and hollow circular shafts -
closely coiled
helical springs.
UNIT V BI AXIAL STRESSES 10+3
Stresses in thin circular cylinder and
spherical shell under internal pressure - volumetric Strain. Combined loading -
Principal Stresses and maximum Shear Stresses - Analytical and Graphical methods.
TOTAL: 60 PERIODS
