Axi-symmetrical deflection and buckling of circular porous-cellular plate

Elastic buckling and static bending of shear deformable functionally graded porous beam

“…The influence of unstable regions for the Mathieu equation was described. She [29,30] also examined the non-linear dynamic stability and axi-symmetrical deflection and buckling of circular porous plates. Belica and Magnucki [31,32] investigated the dynamic stability of a porous cylindrical shell under different loading conditions and obtained the critical loads for a family of porous shells.…”

Non‐linear hypotheses of deformation of flat cross sections of elastic sandwich beam.

“…Magnucka-Blandzi & Magnucki [6] carried out analytical investigations of strength and stability of sandwich beam with a metal foam core under consideration of a non-linear hypothesis of deformation of flat cross section of the structures. The subject of a research is simply supported sandwich beam under uniformly distributed load.The paper is a continuation of the papers Magnucka-Blandzi & Magnucki [6] and Magnucka-Blandzi [7].…”

“…The core is porous inside with the degree of porosity varying in the normal direction. The moduli of elasticity in the core are defined as follows [6,7]:…”

Elastic buckling of a sandwich beam with variable mechanical properties of the core

“…Kardomateas et al [35], Kueh [36], Kwaśniewski and Ziółkowski [37], Leotonig et al [38], Magnucki [28], Ostergaard [39] studied various cases of buckling of sandwich columns. Buckling of composite sandwich structures was described by Magnucka-Blandzi [40], Rivalant et al [41], Teter and Kolakowski [42]. Numerical (FEM) investigations of buckling of sandwich structures were conducted by Bazant and Beghini [25], Dębowski et al [16], Kwaśniewski and Ziółkowski [37], Pokharel and Mahendran [43], Veedu and Carlsson [44].…”
