This article introduces the experiment through which the capacity and influence factor of steady apparatus were tested, the formula between the agitator's end point deflection and the deflection measured actually was derived,the formula between deflection and flow power was reckoned.

In order to study fracture property of RCC and cracking condition of induced joint,three point banding beam fracture tests of RCC have been carried out in this paper. Some parameters and typical curves of fracture property are obtained, such as tensile strength, compressive strength, fracture toughness, fracture energy, curve of load vs. load point deflection, and curve of load vs. crack jaw opening.

Through nonlinear cracking calculation of three point bending beam, the curve of load vs. load point deflection is used to deduce the tensile strain softening curve. Furthermore, the tensile strength of material is modified on 3-D condition. Finally, the cracking calculating condition in numerical calculation of induced joint is established, which is based on the ficititious crack model.

Within the factor scope of this test,it is found that the(load)-(middle point deflection of the specimens) curves can be defined as the following stages: elastic stage,elastic-plastic stage,plastic stage and descending stage.

Within the factors scope of this test,the P(load)-(δ middle point deflection of the specimens) curves can be defined as the following stages:elastic stage,elasto-plastic stage,plastic stage and softening stage.

In this paper, the laws of boundary control of Euler Bernoulli beam with structural damping of Voigt type have been given with feedback information from the end point deflection velocity and deflection angular velocity of the beam.

The fracture energy is determined from the area under the complete load: load-point deflection diagram.

It has been established that the experimental data obtained by the method of three-point deflection of short beams does not characterize their interlaminar shear strength.

Load against load point deflection curves are obtained at loading rates of 5 mm min-1 and 500 mm min-1 using a tensile testing machine.

A number of planar configurations of the redundant manipulator were taken into consideration for the present study and the configuration which gives minimum end-point deflection has been recommended for the critical manipulation.

In this paper the end-point deflection of hyper-redundant robots have been studied by parameterization of the flexible links of the robot manipulator.

The buckling of composite laminate with stiffeners under loads in plane (axial compression、 shear and loads combined compression and shear) is investigated by means of the triangular finite difference method and energy variational principle in this paper. For the problem under study,the normal simple and clamp support boundary conditions are considered, but the lateral deflection springs and bending springs are used as well to simulate the elas-tic support boundary conditions.

The buckling of composite laminate with stiffeners under loads in plane (axial compression、 shear and loads combined compression and shear) is investigated by means of the triangular finite difference method and energy variational principle in this paper. For the problem under study,the normal simple and clamp support boundary conditions are considered, but the lateral deflection springs and bending springs are used as well to simulate the elas-tic support boundary conditions. The buckling governing equation in matrix is deduced in detail, in which the eigen values are loads in plane and the eigen vectors are difference point deflections. Numerical results are given for several kinds of composite laminates with stiffeners under loads in plane and compared with experimental results.
