Assessing factors affecting the flexural behavior of metallic foam in-filled sandwich panel

194-199The performances of metallic foam are required to improve under flexural loading condition to fulfill the industrial need. In the present work existing literature has been evaluated to understand the factors (foam density, span length, aspect ratio of test specimen, foam core and face sheet thickness) affecting flexural property of foam in-filled sandwich panel. Delamination of foam in-filled sandwich panel has been reported as the major failure mode during the flexural test. It has also been reported that the metallic bonding between metallic foam and face sheet avoid the chance of delamination under flexural loading conditions. There is also a need to have standard test procedure and standard test geometry to evaluate flexural property of metallic foam in-filled sandwich panel. Its evaluation using FEM based techniques are also reported in brief

Age hardening behaviour of 2014 Al alloy-SiC composites: Effect of porosity and strontium addition

79-85The aging characteristics of 2014 aluminum alloy-SiC composites with and without strontium addition are studied and compared with that of 2014 Al-cenosphere syntactic foam (Al-Cenosphere composite) and 2014 alloy-SiC composite foam in order to examine the effect of strontium addition and porosity on aging behavior. It is observed that primary peak aging time of strontium added 2014 Al-SiC composite is same to that of 2014 Al-SiC composite. But, strontium added 2014 Al-SiC composite shows secondary ageing unlike that of 2014 Al-SiC composite. Again, 2014 Al-SiC composite foam and cenosphere added syntactic foam get peak aged almost at same time, But relatively at slower rate than dense composites. It is observed that the strontium added composite also showed a peak at 10 h for secondary hardening due to delayed precipitation of AlSr3
