A micromechanical fracture analysis to investigate the effect of healing particles on the overall mechanical response of a self-healing particulate composite

A computational fracture analysis is conducted on a self-healing particulate composite employing a finite element model of an actual microstructure. The key objective is to quantify the effects of the actual morphology and the fracture properties of the healing particles on the overall mechanical behaviour of the (MoSi2) particle-dispersed...

Voxel-based additive manufacturing of biomimetic hard-soft materials: A fundamental study on the effect of biomimetic design parameters on fracture properties

The fracture properties of natural materials often outperform artificial material properties. This could be explained by their complex multi-scale (anisotropic) hard-soft material structure, starting at a nano-scale. The interest in the fabrication of complex biomimetic hard-soft materials and interfaces is growing due to their high fracture...

Effect of pre-existing microstructural defects on elastic and fracture properties of composites

The objective of this research is to explore the effect of microstructural defects on the mechanical properties of fiber reinforced composites. In particular, two kinds of defects are considered in the study, namely, matrix pores and interface precracks. Three-dimensional (3-D) finite element analyses are conducted on Representative Volume...
