“…Side grinding force can be subdivided into chip formation force, ploughing force, friction force, and fracture force of silicon carbide particles (SiCp) [6,7,11,13,14]. The ploughing force is neglected in this numerical model as it is much lesser than the other forces [15].…”

“…Cracking damage of the ceramic particle is assumed to be controlled by the stress in the particle and the statistical behavior of the strength of the particle [6,10]. So based on Griffith theory, the change in the potential energy of the composite due to the debonding damage is a function of the volume fraction of the SiC particles and the material properties, as shown in Eq.…”

“…There are a few studies focused on the prediction model of cutting forces in cutting or conventional grinding of metal matrix composites (MMCs) [6][7][8][9][10][11][12]. Kishawy et al [6] presented an energy-based analytical force model in orthogonal cutting of SiCp/Al composites to predict cutting forces. In this model, the energy for interfacial debonding is quantified.…”

Ultrasonic vibration assisted grinding is an advanced method for machining difficult-to-process materials such as SiCp/Al composites. This paper presents a mechanics model for predicting grinding forces in ultrasonic vibration assisted grinding of SiCp/Al composites. It consists of side grinding force model and end grinding force model. In side grinding force model, the major components are the normal force and tangential force in which the analytical expressions for the chip formation force based on Rayleigh's probability density function, the frictional force, and the particle fracture force based on Griffith theory are established, respectively. In contrast, the axial force developed based on the indentation theory is the major component in end grinding force model. The coefficients in the proposed grinding force model were obtained through two groups of orthogonal experiments. Based on the mechanics prediction model, the relationship between grinding forces and process variables were predicted. At last, two groups of single factor experiments were conducted to verify the proposed grinding force model and experimental results were found to agree well with predicted results.

“…Both types of actions should be taken into account simultaneously and can be interpreted as local mode II (shear mode) and mode I (normal mode) of fracture. Wiggins and Malkin (1978) proposed a fracture based chip formation model in the orthogonal machining of bone and Kishawy et al (2004) considered the energy of fracture for the interfacial debonding of particles in the orthogonal cutting of metal matrix composites. Atkins (2003Atkins ( , 2005 firmly established that the fracture terms are important in any cutting analysis.…”
