Unformatted text preview: Stress and Shear Strength CE2004 What well cover Stress in soils Combined stresses Shear strength Measurement Mohrs Circle Stress in soil: components Load Stress on a plane = Normal stress + Shear stress and vary depending on the plane being considered Can use this approach to identify ..within soil On what plane will be maximum and be zero Planes are perpendicular Principal stresses working on planes 1 2 3 Normally taken as equal to 1 or 3 . Determining and for different planes 1 1 3 3 Take area of this plane as unity (1) F n = n x area = n x 1 = n Area = 1 x sin Area = 1 x cos F 1 = 1 x area = 1 cos F 3 = 3 x area = 3 sin n = n x1 Determining stress on a random plane where principal stresses are known Shear force on plane n n = 1 cos sin 3 sin cos = ( 1- 3 ) sin cos Maximum shear occurs on plane at 45 from principal plane with magnitude: n = ( 1- 3 ) Soil resistance to shear...
