英文摘要：

Porous Cu-Al-Al2O3 composite mechanics model was established and porous Cu-Al-Al2O3 composite shear modulus constitutive equation was obtained by means of Visco-elastic theory and finite element analysis method. The relationship between stress and displacement of porous Cu-Al-Al2O3 composite was attained, and the relationship between support reaction at force surface and load time is non-linear relationship, and porous Cu-Al-Al2O3 composite is viscoelastic material. Access to a result of Cu-Al-Al2O3 composite elastic modulus of porous materials for 533.89 MPa.
