Abstract
The post-buckling behavior of poroelastic columns subjected to axial compressive forces is investigated. The fluid-saturated poroelastic columns are permeable in the longitudinal direction and impermeable in the transverse directions as a result of the microgeometry of the material. The time-dependent behavior of the columns is governed by three coupled equations, obtained using the large deflection theory. These equations are transformed into a single one, enabling the analytical derivation of the initial and the final responses. It is shown that unlike the quasi-static response obtained by using the small deflection theory, the long time response derived here is bounded. The imperfection sensitivity of these columns is also investigated.
