CE3402 STRENGTH OF MATERIALS

L T P C: 3 0 0 3 | Total Hours: 45 Periods

COURSE OBJECTIVES

• To learn the fundamental concepts of Stress in simple and complex states and to know the mechanism of load transfer in beams and the induced stresses due to simple bending and unsymmetrical bending and to determine the deformation in determinate beams and to know the basic concepts of analysis of indeterminate beams.

UNIT I: SIMPLE AND COMPOUND STRESSES

Stresses in simple and compound bars - Thermal stresses - Elastic constants - Thin cylindrical and spherical shells - Biaxial state of stress - Principal stresses and principal planes - Mohr's circle of stresses - Torsion on circular shafts.

UNIT II: BENDING OF BEAMS

Types of beams and transverse loadings- Shear force and bending moment for simply supported, cantilever and over-hanging beams - Theory of simple bending - Bending stress distribution - Shear stress distribution.

UNIT III: DEFLECTION OF BEAMS

Double Integration method - Macaulay's method - Area moment method - Conjugate beam method - Strain energy method for determinate beams.

UNIT IV: INDETERMINATE BEAMS

Propped Cantilever and Fixed Beams - Fixed end moments reactions, slope and deflection for standard cases of loading - Continuous beams - support reactions and moments - Theorem of three moments - Shear Force and Bending Moment Diagrams.

UNIT V: ADVANCED TOPICS

Unsymmetrical bending of beams - shear center applied - Thick cylinders - Theories of failure - Principal stress, principal strain, shear stress, strain energy and distortion energy theories - application problems.
