VariableStructureConclusion

Material arrangementI, IIStructure IStructure II
Low damage of SiC; tensile stress at the interface aggravates the damage of material; the overall stress of the structure fluctuates sharply.High damage of SiC; the stress of interface is small and the transition is gentle; TC4 and UHMWPW have uniform stress distribution.
III, IVStructure IIIStructure IV
Low damage of SiC; stress and stress fluctuation are small.High damage of SiC; tensile stress at the interface; large deformation of MR.

MR layerI, IIIAfter adding MR, the damage degree of SiC, stress, and stress fluctuation is significantly reduced, stress transition at the interface is smooth, and there is no tensile stress.
II, IVAfter adding MR, the stress of MR and UHMWPE is more uniform but tensile stress appears.
