The final deformation of the whole structure shows deflection in the middle, caused by the viscoplasticity of the material:

In comparison with the initial shape, the bridge shrinks 7.59 mm (length) x 2.35 mm (width) x 2.99 mm (height).

The relative density of element A remains unchanged before the sintering process, increases sharply after sintering is activated, and finally approaches 1.0 at the end of the solution:

The grain size of element A experiences rapid growth at the beginning of the sintering process, and later slows down, following the standard parabolic grain-growth behavior:

Figure 66.10: Grain Size of Element A Over Time

After the sintering process, grain size continues growing to a size of 12 um. The midway plateau of the grain size is associated with the staged parameters applied to the grain-growth evolution equation (that is, a substantial increase in the grain-growth energy above 1200℃).
