4. The relationship between composite modulus EC calculated using method of weighted mean and ESP calculated according loading test data is derived, that isESP =0.33 EC +3.6.

Through experimental and theoretical analysis,this paper arrives at a conclusion that the dynamic distribution of power caused by the increase of load in the vibration cutting is an important reason for the gradual degradation of the amplitude of ultrasonic wave. Two mathematical expressions are obtained through the theory analysis from the angle of power budget.

Also, a formula for calculating load frequency in each step is derived by using the linear accumulated damage theory and the equal damage theory when the integrated and accumulated frequency curve yields step spectrum.

The circuit stabilizing the pulse energy due to recuperation of the unused energy in the filter capacitor of the power supply is used to stabilize the energy dissipated by the load.

The electronic (ionic) baroelectric contact potential difference is determined by the work done by the load on changing the electrode volume upon the removal of one electron (ion).

Firstly, the designed HT can realize regulating the pressure, and its output pressure is determined by the control angle of the port plate and affected by the load.

In addition, the performance of VS method is impacted by the load variation in normal operation in which the distributed generator is operated in parallel with the main grid.

Results also show that the debonding at the fibre-matrix interface is influenced by the load-displacement relationship for the lateral loaded curved systems.

This paper deals with reflective high-sensitivity moire interferometry, a new method of experimental mechanics. A phase-type blazed specimen grating of 600 lines/mm was for the first time used. Under the illumination of two coherent collimated beams, the real-time method and the double-exposure method with optical filtering were employed. The interference patterns of U- and V- displacement fields of the surface of test -piece caused only by the loading levels (or their difference) were obtained respectively....

Under the illumination of two coherent collimated beams, the real-time method and the double-exposure method with optical filtering were employed. The interference patterns of U- and V- displacement fields of the surface of test -piece caused only by the loading levels (or their difference) were obtained respectively. The fringe-multiplication factor was 2, carrier pattern being of 10-20 lines/mm. The typical experimental corroboration was presented and examples of application given.

This paper deals with the additional "structural strength" caused by the secondary consolidation of clay in subsoils.Two problems are covered in this paper. On the first one, the mechanism of yielding pressure PCQ for quasi- overconsolidated clay (QOC clay) is discussed.Then, the "Overshoot" of compression curves for aged clay was tested. It is verified that such a phenomenon is an essential behaviour for QOC clay. On the second one, the comparison of stress-strain-strength characteristics between QOC clay and...

This paper deals with the additional "structural strength" caused by the secondary consolidation of clay in subsoils.Two problems are covered in this paper. On the first one, the mechanism of yielding pressure PCQ for quasi- overconsolidated clay (QOC clay) is discussed.Then, the "Overshoot" of compression curves for aged clay was tested. It is verified that such a phenomenon is an essential behaviour for QOC clay. On the second one, the comparison of stress-strain-strength characteristics between QOC clay and OC clay was performed, and it is shown that an essential distinction between the quasi-over-consolidation characteristics due to aging and the overconsolidation characteristics due to unloading is presented.

Based on equi-damage condition,the authors derive an algorithm for determining each step load and its frequency,which may directly generate the step load spectrum from the probability density function of the load.
