✦ Synopsis
Expressions are derived to calculate the limiting thickness of cohesive material which will flow down an inclined plane and the limiting span for flow of a cohesive material between inclined parallel walls.
Flow will not occur in either case if the angle of inclination to the horizontal is less than both the angle of internal friction of the material and the angle of sliding friction of the material with the walls.
The application of the formulae for the limiting thickness of material on an inclined plane is restricted if there is a tension cut-off. Otherwise they can be used for angles of inclination to the horizontal up to W, when the material is hanging from the underside of the plane.
Formulae for the limiting span between inclined parallel walls a.re conservative from the point of view of allowing flow to occur. They are based upon the principle that stresses within the material must be compressive.
