Embodiment 1
[0047] Example 1: Two-dimensional finite element modeling of cold-sprayed SiC-reinforced magnesium alloy composites.
[0048] Composite materials usually contain more than two components. This example shows the modeling of composite materials with three components in the present invention. Multi-level scale triangular meshes and quadrilateral meshes are used in the model. For single-component, coarse Larger meshes are generated automatically for regions with complex components and finer structures, while finer meshes are generated for regions with complex composition and fine structure. This example can verify the two-dimensional grid division ability of the present invention for multi-component materials.
[0049] Adopting the present invention to carry out two-dimensional finite element modeling to the magnesium alloy composite material reinforced by cold spraying SiC, comprises the following steps:
[0050] (1) Obtain a two-dimensional polished cross-sectional image that c...
