Unit – II Simple Stresses, Strains & Elastic Constants

• Define shear strain and modulus of rigidity.
• State the relation between Young’s modulus and Bulk modulus.
• Draw a stress-strain curve for ductile material showing salient points on it. Also, define yield stress and ultimate stress on it.
• Define Poisson’s ratio and state the relation between three elastic constants E, G, and K.
• Define Creep and toughness.
• Define stress and strain and state its S.I. unit.
• E = K. Calculate E/G & Poisson’s ratio for a certain material.
• In a tri-axial stress system, the stresses along the three directions are σx = 100 N/mm2 (tensile), σy = 60 N/mm2 (tensile), and σz = 30 N/mm2 (compressive). Find the strains in each direction. Take E = 2 × 105 N/mm2 and μ = 0.25. If X = 400 mm, Y = 150 mm, and Z = 300 mm. Also calculate the volume change.
• Neat sketches show the failure of the rivet in single-shear and double-shear. Also, write the formulae to calculate shear stress for each case. Assume the diameter of the rivet = d.
• A steel tube of 40mm inside diameter and 4 mm metal thickness is filled with concrete. Determine the stress in each material due to an axial thrust of 60 KN. Take E for steel = 2.1 x 105 MPa. E for concrete = 0.14 x 105 N/mm2
• A metal bar 200 mm long, 40 mm × 30 mm in cross-section is subjected to stress of 110 MPa along the length and 50 MPa on the other two faces. All stresses are tensile. Calculate strains along the three directions and also the volumetric strain. Assume E = 120 MPa and μ = 0.30.
