Abstract:

The computer program THIN obtains the solution of the equations of equilibrium governing the small deflections of thin spherical shells using an algorithm called Dynamic Relaxation. It is assumed that the material properties of the shell are constant and that the shell is closed at the apex. The conditions at the outer edge can be chosen to be either clamped, simply- supported or supported on a transverse roller-skate. This report describes the inputoutput requirements of the program, the behavior of the Dynamic Relaxation algorithm and estimates the accuracy of the program by comparing numerical results obtained using THIN with either exact analytical solutions or analytical solutions where accuracy can be assessed.
