A study on the static analysis of a naval panel made composite sandwich materials is presented. By using FEM, modeling floor with length 5 m and width 2.5 performed. Two distinct cases, have been performed: first model consists plate stiffeners steel second concerns material type / SANFoam103 steel, steel. parametric has The thickness faces 6 mm, for core SANFoam selected thicknesses 10 20 40 mm.

This study presents an innovative design for a cold-formed steel polyurethane (CFS-PU) composite wall panel, combining frame, foam infill, and gypsum fibreboard sheathing. The filling process, in which the is injected under pressure, ensures uniform distribution, bonding, interaction of all panel components. aim to evaluate behaviour CFS-PU panels influence PU sheathing on performance CFS frame...

Composite sandwich materials have yet to be widely adopted in the construction of naval vessels despite their excellent strength-to-weight ratio and low radar return. One barrier to their wider use is our limited understanding of their performance when subjected to air blast. This paper focuses on this problem and specifically the strength remaining after damage caused during an explosion. Carb...

An analytical investigation is conducted to predict the post-buckling strength of laminated composite stiffened panels under compressive loads. When a stiffened composite panel buckles, the skin would deform into a sinusoidal mode shape, and hence induces additional moments and forces near the skin-stiffener interface region. These induced loads would cause the existing small edge delamination ...

Bipolar disorder (BD) is a debilitating mental disorder that cannot be diagnosed by objective laboratory-based modalities. Our previous studies have independently used nuclear magnetic resonance (NMR)-based and gas chromatography-mass spectrometry (GC-MS)-based metabonomic methods to characterize the urinary metabolic profiles of BD subjects and healthy controls (HC). However, the combined appl...

The design of stiffened, composite wing panels must satisfy a range of requirements related to performance, economy and safety. In particular, the design must be damage tolerant to satisfy a number of different performance requirements for various states of damage. To obtain an optimum configuration that satisfies these requirements simultaneously, optimization code PANOPT was extended with a m...

The objective of this paper is to present a method for the design of solid wood panels with cross layers. The stress distribution in and the deformation behaviour of solid wood panels were analysed using the composite theory. The shear influence in solid wood panels was determined using the shear analogy method. A strength class system is proposed for the design of solid wood panels with cross ...
