Overview:
The model is shown in Figure 1 as the total structure. This is a beam that is 25mm by 50mm cross-
section that is 400mm long. The element consists of a meshing size of ten separations. The loading that
is applied is in the center of the beam at 10000N, which applies a bending stress on the beam, which is
seen in Figure 2. At key point 1, the point is constrained in all degrees of freedom.at the other end, key
point 2, the constraint is only applied in the y axis, due to the point being a roller point.
Figure 1: The total structure rendered with correct cross-section.
Figure 2:The deformation in the beam with the outline of the original dimensions.
Analysis:
Below, the results are shown. The nodes experience strain, with the maximum being experienced in
node 7. Node 1 experiences a moment force that is displayed in the bottom results. The forces that act
in each node can also be reviewed below. Here, the increase of displacement can be seen closer to the
center of the structure at node which agrees with the deformation of the structure in Figure 2.
