It can be observed from the stress nephogram
that non-uniform wind pressure exists.
of stress thermal structure coupling, because under the influence of temperature stress, steam autoclave at room temperature is more obvious than in the structural analysis of large, therefore in the autoclave stress-strain analysis, the temperature should not be neglected.
Tensile Load: A stress nephogram
indicated that the ACL internal fibers tensile stress was distributed unevenly.
of the morphology and the axial strain distribution of the samples at a certain time are shown in Fig.
The stress nephogram
in a single roll-beating is shown in the Figure 8, and the corresponding deforming force is shown in the Figure 9.
are showed in Figure 3(g) and (h) to observe the change in the stress.
Nephograms in Figures 10(b) and 10(d) indicate that displacements at both the tunnel roof and bottom are greater after excavation, horizontal and vertical displacements are distributed symmetrically about the center of the tunnel and the vertical displacement at the vault and bottom increased with a decrease in the buried depth of the calculated nodes.
Nephograms shown in Figures 10(a) and 10(c) indicate that the maximum displacement of the surrounding rock mass appeared on tunnel floor and heaving displacement at the inverted arch was as much as 22.
Comparison of the nephograms shown in Figure 11 indicates that the seepage significantly contributed to an increase of the maximum principal stress and it also was found that the maximum principal stress below the tunnel floor is apparently greater than that at the tunnel roof when seepage is considered.

Stress distributions were directly revealed by plotting stress nephograms.
Stress nephograms revealed that the maximum von Mises stress of each material was not near the broken ends of fractured bone.
