Elastic stability of columns on partial elastic foundations under subtangential loading

Divergence and flutter instability of a cantilevered beam on a partial elastic foundation subjected to a subtangential load at the free end are investigated. The dependence of divergence and flutter critical loads on the tangency coefficient is studied parametrically to illustrate the effects of the extent, position, and modulus of the partial foundation. Particular attention is paid to the stabilizing and destabilizing effects of the various parameters.
