Sandwich structures

The main aim of this work is to use a finite element method (FEM) based on Shi’s third-order shear deformation plate theory (TSDT) to study the dynamic response of sandwich plates subjected to consecutive blast loading. The sandwich plate has an auxetic honeycomb core and two different functionally graded materials (FGMs) skin layers (so-called h-FGS plates).

Lightweight structures with soft inclusion material, such as hollow core slabs, foam sandwich wall, pervious pavement are widely used in construction engineering for sustainable goals. Voids and soft inclusion can be modeled as a very soft material, while the main material is modeled with its original rigidity, which is so much higher than inclusion’s one.

This paper deals with the free vibration and dynamic responses of composite sandwich plates. The sandwich plate has three layers in which two face sheets are made of isotropic material, and the core layer is made of auxetic honeycomb structures with a negative Poisson’s ratio.

The aim of this Master of Engineering (MEng) - Aerospace thesis is to study the structural response and failure of aerospace grade composites during exposure to fire. Key aspects of the research are to analyse the thermal and mechanical responses of laminates and sandwich composites in high temperature and fire environments, which result in softening and structural failure. The research is concentrated on carbon/epoxy laminates and sandwich composites, which are the most common composite materials used in aerospace structures.

This research investigates the ‘stateless income’ tax strategies pursued by firms publicly listed in the United States. Stateless income strategies are employed by multinational corporations, American firms in particular, through a Double Irish Dutch Sandwich structure to reduce tax liabilities. By examining 700 listed U.S. firms over the period 2004-2013, this research finds that larger firms with higher levels of foreign income are more likely to adopt the Double Irish Dutch Sandwich structure.

The Payas region bauxite deposits occur as a sandwiched layer that is a few kilometers long and an average of 10 m thick between the lower and upper Cretaceous carbonates of the Arabian Platform. The bauxites occur as 2 types, comprising blanket and pocket, are chemically and texturally homogeneous, and have a thrust structure with ophiolitic mélange formations. The bauxite varies in color, from reddish-brown to grayish-green to black, and has a massive, patchy, and very rare oolitic-pisolitic texture.
