fiber metal laminates (fmls) are new composite materials consisting of thin metal layers and high strength composite layers. arall (aramid aluminum laminate) is a family of the fml that consists of thin aluminum sheets along with kevlar/epoxy composite layers. this material has many advantages such as light weight, excellent corrosion, fatigue and impact resistance. since, arall is a new materi...

The study carried on in this paper draws its motivation from the problem of the asymptotic description of nonlinearly elastic thin films with a fast-oscillating profile. The behaviour of such films is governed by an elastic energy, where two parameters intervene: a first parameter ε represents the thickness of the thin film and a second one δ the scale of the oscillations. The analytic descript...

Elastic boundary conditions play an important role in the buckling analysis of cylinders under compressive loading. These structures are used widely aerospace applications and highly sensitive to geometrical, material, loading, imperfections. In fact, presence these imperfections can lead catastrophic failure. 1968, NASA reported relations for obtaining Knockdown Factor (KDF) based on empirical...
