Abstract
This study aims at characterising the compressive damage mechanisms occurring in syntactic foam containing micro-glass spheres. For this purpose, X-ray micro-computed tomography integrated with an in-situ compressive testing stage was employed for acquiring three-dimensional images at different stages of
compressive strains. It has been found that damage is initiated at the weakest micro-spheres. When uniaxial applied strain is increased, shear collapse bands (SCB) develop around the fragmented micro-spheres due to stress concentration. SCBs are thickened with increase in compressive loading.
