This paper deals with an analysis of a crack-tip field of particulate-reinforced composites which can describe the evolution of debonding damage, matrix plasticity and particle size effect on deformation and damage. Numerical analyses were carried out on a crack-tip field in elastic-plastic matrix composites reinforced with elastic particles by using a finite element method developed based on an incremental damage theory. The particle size effect on damage is described by a critical energy criterion for particle-matrix interfacial debonding. The effect of debonding damage on a crack-tip field is discussed based on numerical results. The debonding damage initiates and progresses ahead of a crack-tip. The stress distribution shifts downward in the debonding damage area. It is concluded that a crack-tip field is strongly affected by debonding damage.

Fluidity Test

Aluminum boron carbide particulate reinforced composites are advanced materials which have superior mechanical properties, and especially have the capability to capture neutrons. The liquid mixing process is one of the methods to produce economically and effectively the metal matrix composites. However, it was found that the fluidity of the composites was instable during liquid holding and casting. To examine the fluidity evolution over the time, the melt of an Al-10%B4C composite was hold at a constant temperature for a long period, and the fluidity was evaluated by means of a vacuum fluidity test. The microstructure of the fluidity test samples was examined by optical and electron microscopes. It is found that the interfacial reaction products between B4C and Al-matrix play an important role for the deterioration of the composite fluidity.
