This paper presents the results obtained with the simulations of a sandwich rectangular plate made of carbon/epoxy composite when subjected to temperature and humidity cycles. Fickian diffusion process, moisture transport along the interfaces and damage caused by slipping and debonding between the components of the microscopic structure are considered. The application of the design methodology ...

The theory of stability of multilayered continua is extended to include the effect of gravity and the case of viscoelastic materials. It is also applied to obtain numerical solutions for the buckling of the anisotropic plate in finite elasticity with free boundaries or embedded in an infinite medium. In the multilayered system it is shown that the effect of gravity forces may be included by a v...

This article provides a fully analytical approach for nonlinear equilibrium path of rectangular sandwich plates. The core of structure is made of symmetric cross-ply laminated composite and the outer surfaces are piezoelectric actuators which perfectly bonded to inner core. The structure is subjected to electro-thermo-mechanical loads simultaneously. One side of plate is rested on Pasternak typ...

Studying the mechanical behavior of metal cores provides insight into the overall performance of structures comprising metal sandwich plates, and can help immensely in designing metal sandwich plates for specific engineering applications. In this study, the response of folded (corrugated) plate and pyramidal truss cores are explored under both quasistatic and dynamic loadings. In particular, tw...

The process of stress accumulation near earthquake faults during the aseismic period in between two major seismic events in seismically active regions has become a subject of research during the last few decades. Earthquake fault of finite length of strike-slip nature in a viscoelastic layer over a viscoelastic half space representing the lithosphere-asthenosphere system has been considered her...

Survival of a plate against an intense, short duration impulsive loading requires the circumvention of failure modes, including those associated with excessive overall deflection and shear-off at supports and webs. All-metal sandwich plates have distinct advantages over comparable weight monolithic plates, especially for intense water loadings. A recently developed mechanics of dynamically load...

Abstract When subjected to bending loads, sandwich panels are highly efficient structural components with the potential achieve substantial weight reduction. A successful design methodology for should aim at maximising this reduction while considering various possible failure mode in a simple yet accurate manner. This paper investigates application of steel as two-way deck systems. Near-optimal...
