Current situation of processing technology for producing aluminum plate,strip and foil in China and abroad,particularly the domestic industrial structure of aluminum products are reviewed. Based on the comparison between aluminum cast-rolled blank and hot-rolled blank,the technology for manufacturing hot-roll big-sized aluminum plain ingots in Yunnan is discussed.

The paper pointed out cleaning process is key to improve the surface quality of aluminum plate,strip and foil. The process flows,equipment and characteristics contrast of water cleaning and grease cleaning are emphasized. It says that grease cleaning process is advantageous in many aspects,and gains more concerns by aluminum processing industry.

The present situation of China's aluminum FRPs industry has been generalized. The China's demand,import and export quantities of the aluminum plate,strip and foil have been forecast.

As an example, an approximate analytic solution of nonlinear vibration for a plate strip in lateral magnetic field is obtained by the multi-scale method.

[Methods] The sandwich TRFIA for detection of serum GH level using two anti-GH mAbs (One monoclonal antibody was immobilized on the surface of microtiter plate strip wells, another was labelled with Eu3+).

METHODS: The sandwich TRFIA was established for detection of serum CK-MB level using anti-CK-MB mAbs(One monoclonal antibody was immobilized on surface of microtiter plate strip wells,and another was labelled with Eu~(3+)).

The large elastoplastic deflection analysis in the pinch - type four - roll plate bending process is developed in [ 1 ] for a plane strain plate strip made of ideally plastic materials, and generalized in this paper to the materials of general strain hardening law.

Thermal stress in a plate strip induced by local heating

It is established that these dispersion equations and the dispersion equations for a semiinfinite orthotropic plate strip are in an asymptotic relationship.

The fundamental frequency of a clamped composite plate strip with either one free macrocrack or two parallel free cracks is determined using the exact equations of the theory of elasticity.

Natural Vibrations of a Composite Plate Strip with Macrocracks

The stability of a long plate (strip) made of a layered composite with a curved structure is studied within the framework of the three-dimensional linearized theory of stability.

The subject discussed in this paper is the rectangular plate. Its two opposite edges are simply supported, while the other two are arbitrary, and the rigidity of the plate is variable along the direction parallel to the simply supported edges. In order to solve the problem, the author adopts the finite plate-strip element method, which is different from the usual finite element method or the finite strip method. The steps of the above method is no longer to establish a rigidity...

The subject discussed in this paper is the rectangular plate. Its two opposite edges are simply supported, while the other two are arbitrary, and the rigidity of the plate is variable along the direction parallel to the simply supported edges. In order to solve the problem, the author adopts the finite plate-strip element method, which is different from the usual finite element method or the finite strip method. The steps of the above method is no longer to establish a rigidity matrix for elements or strips and gather them to be a total matrix for solution. Now the relation of transfer between the strain and inner force of every plate-strip is shown. Finally a practical example is given and this method is found to be easier and more effective.

The transverse shearing deformation and rotational inertia are taken into consideration in the chosen thick plate strips.The mode shapes of various orders in the strip are taken as continuous functions along the strip.Three independent variables( one deflection and two rotation angles in two directions) connected in fourth order polynomials are introduced in the transverse direction of the strip.The rotational inertia is counted in the mass matrix used in the analysis.Under blast (or...

The transverse shearing deformation and rotational inertia are taken into consideration in the chosen thick plate strips.The mode shapes of various orders in the strip are taken as continuous functions along the strip.Three independent variables( one deflection and two rotation angles in two directions) connected in fourth order polynomials are introduced in the transverse direction of the strip.The rotational inertia is counted in the mass matrix used in the analysis.Under blast (or static) loading,the dynamic (static) displacements and the dynamic (static) internal forces of structures with thick plates are analyzed by this finite thick strip method.The numerical results of different models are given and compared with analytical solutions and finite element solutions.The advantage of this method is its high accuracy and few degrees of freedom.
