摘要
建立了多孔铜-铝-氧化铝复合材料力学模型.利用粘弹性理论和有限元分析方法,得到了多孔铜-铝-氧化铝复合材料的切变模量本构方程;得出了铜-铝-氧化铝复合多孔材料的压力与位移的关系、受力面的支反力与加载时间的关系是非线性关系,多孔铜-铝-氧化铝复合材料是粘弹性材料的结论;获得了铜-铝-氧化铝复合多孔材料的弹性模量为533.89MPa的结果.
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.
