The principle of coupled stress release model and its application

Coupled stress release model is proposed in the paper considering the interaction between different parts based on stress release model by Vere-Jones, and is used to historical earthquake data from North China.

The results show that coupled stress release model is better than original model.

We apply an improved statistical model of coupled stress release to the synthetic catalog, it does successfully inverse the stress evolution of the system, but effectively prediction of the earthquakes from the stresses remains a problem.

This paper is a development of the quadratic strength criterion of integrated modes for fiber-reinforced composite materials. For simplification of evalution, the Cubic terms of the strength criterion in the reference [1] is neglected. From the point of view of principle, the criterion that includes the cubic terms has better accuracy, but it is not the truncating cubic tensor polynomial expansion. The criterion is mathematically expressed in a general cubic equation in terms of stress invariants. Considering...

This paper is a development of the quadratic strength criterion of integrated modes for fiber-reinforced composite materials. For simplification of evalution, the Cubic terms of the strength criterion in the reference [1] is neglected. From the point of view of principle, the criterion that includes the cubic terms has better accuracy, but it is not the truncating cubic tensor polynomial expansion. The criterion is mathematically expressed in a general cubic equation in terms of stress invariants. Considering two basic failure modes of unidirectionally fiber-reinforced composites, the criterion can be simplified. Two methods for determining cubic coupling coefficients are discused. This criterion has the characteristics more rational and simpler than that in the reference [4], and agre-es better with experimental data.

The perpendicular anisotropy, coercivity and Kerr rotation angle ofthe amorphous Tb_(32)Fe_(54)Co_(14) films were studied. The X-ray, electron diffraction,XPS and AES profile confirmed that no obvious change in their amorphous struc-ture and oxygen concentration is observed after annealing at 100℃, while theirproperties alter evidently under bending stress. It is believed that the perpendicularanisotropy in the Tb_(32)Fe_(54)Co_(14) film mainly arises from the induced stress duringpreparation and the magnetostriction...

It is believed that the perpendicularanisotropy in the Tb_(32)Fe_(54)Co_(14) film mainly arises from the induced stress duringpreparation and the magnetostriction coupling stress, as well as, the thermalinstability of the film is related closely to the stress relaxation during annealing.

In this paper, we make a numerical and simulant calculation of coupled stress and rock strength weakening caused by water seeping after reservoir impounding, using the theory of two—phase porous medium. The results show that due to water seeping, pore pressure in rock increases and coupled stress decraeses, so the effective stress in rock decreases and the shear strength should decrease. The decreasing increment is comparable to the value of the shear stress drop on seismic fault surface. Finally, some possible...
