| Abstract: | The deformation behavior of aluminum
cenosphere syntactic foam (ACSF) as a function of porosity, shell thickness,
shell volume fraction and cenosphere volume fraction has been studied using
finite element modeling of a representative unit cell of the
respective material under both constrained and unconstrained conditions. The
volume fraction of cenosphere and its shell thickness varies from 5% to 65% and
1 µm to 4 µm, respectively. It has been noted that as cenosphere volume
fraction decreases, the plateau stress and Young’s modulus of these materials
increases. While these values increase with increase in the shell thickness,
i.e., shell volume fraction. The modulus and plateau stress increase
considerably under constrained condition especially at low cenosphere volume
fraction. The FEM predicted values are validated with experimental results and
it is noted that the FEM predicted values are within the 12% variation of the
experimental values. The proposed study thus shows that unit representative
shell techniques are reasonably ideal and rapid method for predicting
compressive deformation behavior of ACSF. |
