MECHANICS OF SOLIDS

 LPTC
3003

OBJECTIVES:
• To understand the fundamental concepts of stress & strain and its deformation under loads.
• To analyze the determinate beams and determine shear force and bending moment.
• To apply the mathematical knowledge to calculate the deformation behavior of beams.
• To understand the effect of torsion on shafts and springs.
• To analyze a complete two dimensional state of stress.

UNIT I

STRESS AND STRAIN

9
Stress and strain at a point – Tension, Compression, Shear Stress – Hooke’s Law –Relationship among elastic constants – Ultimate Stress – Yield Stress – Factor of Safety –Thermal Stresses – strain Energy due to Axial Force – Resilience – Stresses due to impact and Suddenly Applied Load.

UNIT II

SHEAR AND BENDING IN BEAMS

9
Beams and Bending- Types of loads, supports – Shear Force and Bending Moment Diagrams for statically determinate beam – cantilever beam – Simply supported beam - with concentrated load - uniformly distributed load


UNIT III

DEFLECTION OF BEAMS

9
Double integration method - Macaulay's methods - Area moment method - conjugate beam method for computation of slopes and deflections of determinant beams.

UNIT IV

TORSION

9
Torsion of Circular and Hollow Shafts – Stresses and Deflection in Circular Solid and Hollow Shafts – strain energy due to torsion – Power transmitted to shaft – Shaft in series and parallel – Closed and Open Coiled helical springs – Springs in series and parallel.

UNIT V

THIN CYLINDERS AND THEORIES OF FAILURE

9
Thin cylinders – Stresses in thin cylindrical shell due to internal pressure – circumferential and longitudinal stresses - Theories of failure - maximum Principal stress - maximum Principal strain - Shear stress - Total strain energy - Energy distortion theories

TOTAL : 45 PERIODS

OUTCOMES:
• Thorough understanding of the fundamental concepts of stress and strain
• Ability to analyze the determinate beams.
• Ability to apply the mathematical knowledge in determining the deformation behavior of beams
• Thorough understanding of the effect of torsion on shafts and springs.
• Ability to analyze a complex two dimensional state of stress and to analyze the failure mode.
