Effective design of a sandwich beam with a metal foam core

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

“…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]:…”

“…Wang et al [5] discussed in details the shear deformable effect of beams and plates and described some special theories of them. 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].…”

Exact solutions for postbuckling of a graded porous beam

“…Jasion and Magnucka-Blandzi [2] investigated the global and local buckling of sandwich metal foam circular plates and beams and the critical buckling loads for these structures were presented and compared with those obtained by other methods. Magnucka-Blandzi and Magnucki [3] gave some optimal parameters in the effective design for a sandwich metal foam beam and the mass and critical load of the beam were considered at the same time in the analysis. Chen et al [4] studied the elastic buckling and bending problems for functionally graded porous beams based on shear deformation theory, two porosity distributions were considered in the analysis.…”

Strength of the Three Layer Beam with Two Binding Layers

“…Małachowski et al [13] presented the experimental investigations and numerical modeling of closed-cell aluminum alloy foam (Alporas). Magnucka-Blandzi and Magnucki [10] optimized the sandwich beam with a metal foam core under strength and stability constrains. Magnucki et al [11], [12] presented the strength analysis of a simply supported five layer sandwich beams with a metal foam core.…”
