The buckling of a swollen thin gel layer bound to a compliant substrate [PDF]

, 2007
Gels are used to design bilayered structures with high residual stresses. The swelling of a thin layer on a compliant substrate leads to compressive stresses.

Singular inextensible limit in the vibrations of post-buckled rods: Analytical derivation and role of boundary conditions [PDF]

, 2014
In-plane vibrations of an elastic rod clamped at both extremities are studied. The rod is modeled as an extensible planar Kirchhoff elastic rod under large displacements and rotations. Equilibrium configurations and vibrations around these configurations

Prescribed pattern transformation in swelling gel tubes by elastic instability

, 2012
We present a study on swelling-induced circumferential buckling of tubular shaped gels. Inhomogeneous stress develops as gel swells under mechanical constraints, which gives rise to spontaneous buckling instability without external force.

A new approach to the stability problem of plates subjected to arbitrary complex loading

Vietnam Journal of Mechanics, 1992
The pre-buckling and post-buckling deformation processes are assumed to be less complicated, i.e. processes of average curvature, the influence of complex loading on the stability of plates was analyzed in [1]. In this paper eliminating this restriction,
