Prestressed assembled monolithic of concrete sandwich plate and it's service specification

In this paper, according to the characteristics of ER fluid, the dynamic properties of a sandwich plate with ER fluid as its core layer were investigated theoretically and experimentally under the condition of small deformation and different applied external electric fields.

in this paper a nine-mode rectangle element of composite sandwich plate isdeveloped and applied to the large deflection analysis of symmetric composite sandwichplates.

Analysis of the forming mechanism and defect during sandwich sheet metal stamping;

The sandwich panel of polyurethane foam is a new structural form which can be widely used in protective engineering,and finite element analysis is executed for the three different types of panels-the sandwich panel of polyurethane foam,the concrete panel glued with steel sheet and the concrete panel under explosive loadings.

To reduce the weight of sandwich panels,using the SQP algorithm, we carried out an optimal design of its geometrical dimension and relative density of metal foams under the constraint conditions of no occurrence of any failure modes of compression sandwich panels.

The vibration responses and damping capacity of the sandwich panels with SMA layers are studied.

Finite element analysis for sandwich plates with moderately thick viscoelastic cores

In this paper a triangular element method of composite sandwich plates is developed for which the bending stiffness and coupling stiffness of faceplates are considered.

Three types of prestressed concrete structural floor systems including waffle slabs,hollow slabs and sandwich plates used in multi-storey and high-rise buildings with large span(or column grid)6～12m are mainly introduced.
