The analytic results indicate that the fiber characteristic value,the FRP laminate structure and the loading method are the three major factors that influence the compressive stress-strain relationships of concrete of the FCCs.
An experiment is carried out with one-third loading method,the mechanical performance of the strength and the modulus of flexural-tensile of geogrid reinforement semi-rigid type base course materials is studied through MTS810 test equipment,a test road is constructed to verify the design method.
The dynamic bend strength 6dwas introduced into the evaluation of the strength property of composites in the Charpy impact test, and compared with the results of three-point bend test which was similar as the previous in loading way.
Tile results show that permeability of intact rock under lower pressure is of 0.001 md magnitude and fractural rock is of 1 md magnitude, and rock permeability is clearly related to stress state and loading way.
The multi-potential surface model in stress space is put forward, and the stress-strain behavior of an element under different loading conditions are simulated based on both the multi-potential surface model and Duncan-Chang’s E-μ model with the same parameters.
Applying this new model for predicting strength, we investigate different lamina properties, lay-up configurations and combined loading conditions’ effects on the strength and draw stress-strain behaviors and failure envelopes of composite laminates and comparative figures between the predicted values and experimental ones for somearrangements of the laminates.
(1) the loading conditions of a composite laminate: fiber direction along loading direction is good for improving the critical buckling load of a composite laminate under the other three aspects that is known.
The fracture mechanisms of wood depend on the mode of loading (Mode I and Mode II) and on the orientation of load application (e.g.
The extent of the effect that changes in the above mentioned parameters have on the post-collision flow responses depends upon the loading mode used.
Some differences in behaviour are found to depend on loading mode and nature of moisture cycling.
The dynamic response shows a significant dependence on the loading mode, the material combination parameters as well as the crack configuration.
Under a given loading mode and a specified crack configuration, the DERR of an interface crack between piezoelectric media may be decreased or increased by adjusting the material combination parameters.
The samples of the nanocrystalline oxide are prepared with the use of the shockwave loading method.
Through the calculation of a inclined crossed R-C frame, the results show that VED is effective in controlling the seismic response of frame and the pseudo-loading method is reliable in the calculation.
The portion-loading method is shown to be effective for processing high-solids slurries.
In this paper, to begin with, the nonlinear differential equations of a truncaled shallow spherical shell with variable thickness under uniformly distributed load are linearized by step-by-step loading method.
A novel droplet-tap sample-loading method for two-dimensional gel electrophoresis
We have studied basic parameters of emission processes as functions of the crack edge velocity, its dimensions and depth in the material with due account of its elastic and strength characteristics and loading conditions.
Effect of Loading Conditions on Informative Parameters and Signal Spectra of Acoustic Emission in Samples of Carbon Steels
The kinetics of damage accumulation in TiN coatings under various loading conditions has been investigated using spectral parameters of isolated acoustic emission pulses and their integral ow characteristics.
Under such loading conditions, the density of two-dimensional (2D) electrons at the heterointerface is determined primarily by a piezoelectric field induced in the  direction.
Under the same loading conditions, the rate of microplastic deformation of ultrafine-grained titanium is lower than that of coarse-grained titanium and the rate peaks shift toward high temperatures.
