Design Stress - an overview ScienceDirect Topics

The permissible design stress ranges (or amplitudes) are presented as independent of the mean stress (expressed by the stress ratio R) in the diagrams of Figs 2.42.7.The argument behind this simplification is the assumption that high tensile residual stresses which keep the propagating crack permanently open are acting in welded components in contrast to small test specimens.DERIVATION OF HOOP STRESS IN THIN CYLINDER -Stress acting along the circumference of thin cylinder will be termed as circumferential stress or hoop stress.If fluid is stored under pressure inside the cylindrical shell,pressure will be acting vertically upward and downward over the cylindrical wall.Cylindrical Pressure Vessel Uniform Internal or External Meridional Stress.Circumferential or Hoop Stress.Radial Displacement of Circumference.Change in height dimension y.Rotation of a meridian from its unloaded position = 0.Where used E = Modulus of Elasticity (lbs/in 2) v = Poisson's ratio 1,2 = stress,(lbs/in 2) t = Cylinder thickness,(in) y = Length of cylinder,(in) R = Radius,(in)
