Plastic Equilibrium in Anisotropic Cohesive Clays

An analysis is proposed for determining the static and kinematic characteristic lines for a medium of anisotropic cohesive clays. It is proved that, similar to the isotropic case, the velocity field and the stress field coincide and their lines intersect at an angle of π/2. The compatibility equations along the slip lines are derived. An adopted strength function containing four degrees of freedom has proved to be in very satisfactory agreement with laboratory tests. The above derivation is applied to determination of the bearing capacity. It is shown that for a considerable amount of anisotropy, a misleading evaluation of the bearing capacity may be reached if the anisotropic phenomenon is disregarded.

The ”Melting Point” of Suppositories.:Device for Testing the Resistance of Fatty-Base Suppositories to Deformation

Fatty-base suppositories, when ideally formulated, melt at body temperature and yet retain their firmness and shape in ordinary storage. It is desirable to have a test procedure which will show the melting behavior of a formulation as a finished suppository. Since a static melting test gives a misleading evaluation of the behavior of a suppository, a procedure is described wherein, by pneumatically applying a slight pressure to a suppository held at a specified temperature, its behavior under use conditions may be better evaluated.
