CE6306 SOM Syllabus, STRENGTH OF MATERIALS Syllabus – MECH 3rd SEM Anna University

OBJECTIVES:
To understand the stresses developed in bars, compounds bars, beams, shafts, cylinders and spheres.
UNIT I STRESS, STRAIN AND DEFORMATION OF SOLIDS 9
Rigid bodies and deformable solids – Tension, Compression and Shear Stresses – Deformation of simple and compound bars – Thermal stresses – Elastic constants – Volumetric strains –Stresses on inclined planes – principal stresses and principal planes – Mohr’s circle of stress.
UNIT II TRANSVERSE LOADING ON BEAMS AND STRESSES IN BEAM 9
Beams – types transverse loading on beams – Shear force and bending moment in beams – Cantilevers – Simply supported beams and over – hanging beams. Theory of simple bending– bending stress distribution – Load carrying capacity – Proportioning of sections – Flitched beams – Shear stress distribution.
UNIT III TORSION 9
Torsion formulation stresses and deformation in circular and hollows shafts – Stepped shafts– Deflection in shafts fixed at the both ends – Stresses in helical springs – Deflection of helical springs, carriage springs.
UNIT IV DEFLECTION OF BEAMS 9
Double Integration method – Macaulay’s method – Area moment method for computation of slopes and deflections in beams – Conjugate beam and strain energy – Maxwell’s reciprocal theorems.
UNIT V THIN CYLINDERS, SPHERES AND THICK CYLINDERS 9
Stresses in thin cylindrical shell due to internal pressure circumferential and longitudinal stresses and deformation in thin and thick cylinders – spherical shells subjected to internal pressure –Deformation in spherical shells – Lame’s theorem.
TOTAL (L:45+T:15): 60 PERIODS

OUTCOMES:

• Upon completion of this course, the students can able to apply mathematical knowledge to calculate the deformation behavior of simple structures.
• Critically analyseproblem and solve the problems related to mechanical elements and analyse the deformation behavior for different types of loads.
