Beams were scaled in the height direction in the first test series and in the length direction in the second series.
Figures 7(a) and 7(b) compare the displacement in the height direction in the major and minor cross-sections between models and to illustrate the effect of nuclear elasticity, which was (a) Pa and (b) Pa.
The cell walls of a honeycomb subjected to in-plane loading are deformed in the height direction due to the effect of Poisson's ratio.
When the in situ stress contrast is 4 MPa, fractures experience less resistance in the height direction, which avails the fracture growth in barriers and consequently decreases the fracture length.
Since these deformations differ between adjacent cell walls if they are not joined along their common edge, the in-plane stiffness should be analyzed in three-dimensions to ensure that deformations in the height direction are considered.
The strain component in the height direction was 11% compressive in the bottom region and decreased toward zero with increasing height.
When the in situ stress contrast is 7 MPa, fracture communication phenomenon happens later because of the increase of propagation resistance in the height direction, which also reduces the fracture width in barrier 2. However, the total fracture length in pay zones becomes larger compared to the last case.
Escalator velocity in the depth direction is 0.5 m/s; that in the height direction (except initial elevation) is 0.25 m/s.
For the finite element analysis results, the two-dimensional (2D) displacement was calculated for nodes at each height range in the unstretched state, that is, and, neglecting the component in the height direction.
Air velocity fluctuations on the outer cylinder of the improved guide blade are decreased in the height direction.
