Study on hyporbolic shear deformation curve of the discontinuous plane in rock mass
2.
By prolonging the deformation curve , we can estimate the tendency of deformation
3.
On the basis of the paper , we write a program to estimate ds and draw deformation curve
4.
Using this program , we can estimate ds and draw deformation curve conveniently . moreover , we can estimate the tendency of the curve evolution
5.
In order to establish the nonlinear elastic model of qi loess , the hump curve was used to stimulate both the softening stress - strain curve and the volume deformation curve
6.
Through iteration for all incremental steps the ultimate load can finally be found . using the present method the ascending segment of the load - deformation curve can be obtained . considering of the effect of stability and material strength
7.
The specimen of the test was stimulated by viscoelastic model and the wheel load was stimulated by special function , which are brought into viscoelastic equation . after solving the equation , we can work out the theoretical answer . thus we can figure out the ds and the deformation curve
8.
Nonlinear constitutive relations are discussed for analyzing the stress distribution , the appearance and development of the cracks , as well as the behavior of the boundary conditions of the two way slabs respectively . in the light of the experimental research on r . c . two way slabs under static loading , the behavior of yield line , the load deformation curves and the crack yield , plastic limit loads of slabs with different supporting conditions are studied
9.
In the paper , by using bp ( back propagation ) method of ann , we can get the relationship between grading , asphalt - aggregate ratio , bulk density , percentage of voids , test temperature and ds . at the same time , we can get the relationship between grading , asphalt - aggregate ratio , bulk density , percentage of voids , test temperature and viscoelastic parameter . at last , we can estimate the ds and draw the deformation curve
10.
The progress of this method can be divided into two steps . one is found the relations of the moment , compression force and the curvature on the base of the balance of the internal force . the other step is to found the relation of the flexibility , corner and the curvature through the elemental deformation curve
