Abstract

This work analyzes the elastic interaction of two spherical-cap cracks at the interface of a hollow particle embedded in a dissimilar medium under remote uniaxial tensile loading. A semi-analytical approach is used to compute stress and deformation fields as functions of particle wall thickness and crack configuration. Strain energy release rates are used to establish conditions for stable crack propagation and shielding. The study is directly applicable to tensile and flexural failure of syntactic foams used in marine and aerospace applications. Results specialized to glass-vinyl ester syntactic foams demonstrate that particle wall thickness can be used to control crack stability, as well as the magnitude of the shielding phenomenon.
