Orthotropic cylindrical pressure vessels under line load

The work carried out earlier in this field is reviewed. Equations of equili brium in terms of displacement components are derived for an orthotropic th in circular cylindrical shell subjected to a load that is not symmetric abo ut the axis of the shell. Solutions that satisfy the boundary conditions ar e assumed in the form of exponential and trigonometric terms. Line loads al ong generator, as well as, circumference are considered. Eighth order diffe rential equations in terms of parameter 'p' are obtained. These equations m ay be solved using suitable numerical methods. (C) 1999 Elsevier Science Lt d. All rights reserved.
