Buckling of Circular Mindlin Plates with an Internal Ring Support and Elastically Restrained Edge

Thermally induced buckling of thin annular FGM plates

“…While the in-plane load is symmetric, the buckled shape of the plate may be asymmetric [24,25,45,46]. To this end, the buckling mode of the plate is considered as [47] where n is the number of nodal diameters. Here, n = 0 indicates the symmetric buckled shape of the plate and n > 0 is (17)…”

Buckling of Annular Plates with Shell-Stiffening and Elastic Restrains on the Boundary

“…and substitute it into (4). We obtain that the amplitudes w o (ρ) and m w n (ρ) should fulfill the following differential equations:…”

“…Laura et al have investigated the buckling of circular, solid and annular plates with an intermediate circular support under the assumption of axisymmetric deformations [2]. By the use of the Kirchhoff-Love plate theory [3] and the Mindlin-Reissner theory [4] Wang and his co-authors studied the same structure under the assumption of non-axisymmetric deformations. Rao and Rao have analysed the buckling of circular plates which are supported along concentric rings.…”
