Objectives :
To familiarize the students with the fundamentals of deformation, stresses, strains in structural elements.
Outcomes :
At the completion of this course, students should be able to
1. Know the concepts of stress and strain.
2. Analyze the beam of different cross sections for shear force, bending moment, slope and
deflection.
3. Understand the concepts necessary to design the structural elements and pressure vessels
Syllabus
UNIT 1:
Stress and strain: stresses in members of a structure, axial loading, normal stress, shear stress,
analysis of simple structures, stepped rods, members in series and parallel: stress strain diagram,
Hooke’s law, stress due to temperature, Poisson’s ratio, Bulk modulus, shear strain, relation among
elastic constants, residual stress, fiber reinforced composite materials, strain energy under axial
loads and stresses due to impact of falling weights. Transformation of stress and strain, principal
stresses, normal and shear stress, Mohr’s circle and its application to two and three dimensional
analysis.
UNIT 2:
Bending: pure bending, symmetric member, deformation and stress, bending of composite sections,
eccentric axial loading, shear force and BM diagram, relationship among load, shear and BM, shear
stresses in beams, strain energy in bending, deflection of beams, equation of elastic curve,
Macaulay’s method and Area moment method for deflection of beams.
UNIT 3:
Torsion in shafts: Tensional stresses in a shafts, deformation in circular shaft, angle of twist,
stepped and hollow transmission shafts.
UNIT 4:
Theories of failures: maximum normal stress & shear stress theory; maximum normal and shear
strain energy theory; maximum distortion energy theory; application of theories to different
materials and loading conditions.
UNIT 5:
Columns & struts : stability of structures, Euler’s formula for columns with different end
conditions, Rankine’s formula.
