In this research, the influence of carbon nanotubes agglomeration on buckling behavior multi-phase CNTs/fiber/polymer/metal composite laminates cylindrical shells under hydrostatic pressure was investigated. Governing equations were derived according to Kirchhoff-Love’s first approximation shell theory and solved by a combination Galerkin Fourier series expansion methods. Equivalent elastic pro...

PURPOSE To investigate the correlation of anterior chamber depth (ACD) with the peripapillary retinal nerve fiber layer (RNFL) thickness, age, axial length (AL), and spherical equivalent in children. SUBJECTS Consecutive subjects aged 4 to 18 were recruited. Visually disabling eye conditions were excluded. Only the right eye was included for analysis. The ACD was correlated with RNFL thicknes...

A new hybrid homogenization approach is proposed for simulating the homogenized and local response of unidirectional fuzzy fiber nanocomposites undergoing inelastic deformations. Fuzzy composites are hierarchical reinforcing structures where fibers coated with radially aligned carbon nanotubes (CNTs) embedded in matrix. In this spirit, modeled as a three-scale medium. At microscale, CNTs-reinfo...

Hierarchical systems can address the matrix-dominated failures of structural fiber polymer composites. Here, a new synergistic hierarchical structure combines conventional glass fibers with bi-continuous silica-based aerogel matrix; both pure-silica and organically-modified silicate aerogels are demonstrated. When infused an epoxy matrix, this type architecture showed marked improvement in mech...
