The effect of duration load testing on flexural properties structural insulated panels was investigated herein. Structural were manufactured by a member the Insulated Panel Association (SIPA) in accordance with International Code Council-Evaluation Service Report 4689. Two panel depths 16.5 cm and 31.1 (6.5 in. 12.25 in.) tested short 1/3-point bending per American Society for Testing Materials...

An analytical investigation on the nonlinear response of doubly curved panels constructed from homogeneous face sheets and carbon nanotube reinforced composite (CNTRC) core subjected to external pressure in thermal environments is presented this paper. Carbon nanotubes (CNTs) are into layer through uniform or functionally graded distributions. The properties constituents assumed be temperature ...

A vibration-damping steel panel is used for lightweight vehicles to block any noise subjected the passenger cabin replacing heavy fiber-based insulators. Conventional weld joining methods often encounter problems due presence of viscoelastic compounds reducing joint quality and making process unproductive. In this work, we present experimental results that show self-piercing riveting (SPR) can ...

wood is a naturally renewable material with both continuous and isolated pore systems. wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. however, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. using nano-materials are very easy in the wo...

Hydrocarbon wells drilled vertically through longwall coal pillars are vulnerable to severe deformation and potential failure as a result of underground coal mining. The lithology of the host rocks play a critical role in well stability. In this study, a two dimensional finite element method is employed to investigate the horizontal shear offset, vertical delamination, and compression at the we...

Progress in establishing an analysis package and design/optimization framework for preliminary design of a civil tiltrotor aircraft is reported. Updates to the sizing/performance program VASCOMP and Equivalent LAminated Plate Solution ELAPS are described. Correlation of this updated ELAPS (now including shear panels) and a state-space unsteady aerodynamic analysis, PWAKE, with reference results...

Metal Plate Shear Walls (MPSWs) represent an effective, practical and economical system for the seismic protection of existing RC framed buildings. They consist of one or more metallic thin plates, bolted or welded to a stiff steel frame, which are installed in the bays of RC framed structures. A case study of an existing RC residential 5-storey building, designed between the ‘60s and ‘70s of t...

Textile Reinforced Concrete (TRC) is a composite material made of open-meshed textile structures and a fine-grained concrete. Comparable to steel reinforcement the textile fabric bears the tensile forces released by the cracking of the concrete. Only a minimal concrete cover is required for the bond of the textile fabrics. Thus, the application of TRC leads to the design of filigree and lightwe...

The goal of the research described in this paper is to investigate the feasibility of a new combined polymer composite damping system, which consists of a polymer honeycomb material and a viscoelastic solid material. This new combined viscoelastic system, which is intended primarily for energy dissipation and vibration control, serves as an interface layer within lightweight composite panels su...
