The buckling analysis of stiffened cylindrical shells by rings and stringers made of functionally graded materials subjected to axial compression loading is presented. It is assumed that the material properties vary as a power form of the thickness coordinate variable. The fundamental relations, the equilibrium and stability equations are derived using the first order shear deformation theory. ...

Many works can be found in the literature concerning the vibroacoustic modelling of submerged stiffened cylindrical shells, because of high interest in the industrial domain, in particular for aeronautical or naval applications. However, only a few of them take into account non-axisymmetric internal frames, as for instance engine foundations or floor partitions, that can play a role on the vibr...

The poly(methyl methacrylate) (PMMA)/poly(methyl methacrylate)–poly(methyl acrylate acid) copolymer (PMMA–PMAA) composite polymer latex were synthesized by the method of soapless seeded emulsion polymerization. The morphology of the composite polymer latex was core–shell structure. The core was PMMA and shell was PMMA–PMAA copolymer. Because the PMMA–PMAA copolymer was shell, the carboxylic aci...

A modified coaxial electrospinning process was used to prepare composite nanofibrous mats from a poly(methyl methacrylate) (PMMA) solution with the addition of different cellulose nanocrystals (CNCs) as the sheath fluid and polyacrylonitrile (PAN) solution as the core fluid. This study investigated the conductivity of the as-spun solutions that increased significantly with increasing CNCs addit...

Conducting damage diagnostics on stiffened panels is commonly performed using a single SHM technique. However, each technique has both its strengths and limitations. Rather than straining the expansion of techniques going beyond their intrinsic capacities, these limitations should instead be considered in application. In this work, we propose novel fusion-based methodology between data from two...
