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.
