“…The current MPM model based on the so called generalized interpolated material point (GIMP) (Bardenhagen and Kober, 2004) method is described in more detail in (Leroch et al, 2018). The clear advantage of MPM over time explicit FEM methods (Woldman et al, 2017) lies in its meshless nature. Since the particles are discrete and interact only via their kernels, the method does not need additional separation formulations to allow for fracture.…”

An efficient optimization of surface finishing processes can save high amounts of energy and resources. Because of the large occurring deformations, grinding processes are notoriously difficult to model using standard (mesh-based) micro-scale modeling techniques. In this work, we use the meshless material point method to study the influence of abrasive shape, orientation, rake angle, and infeed depth on the grinding result. We discuss the chip morphology, the surface topography, cutting versus plowing mode, the material removal rate, and the chip temperature. A generalization of our model from a straightforward single-abrasive approach to a multiple-abrasive simulation with pseudo-periodical boundary conditions greatly increases the degree of realism and lays the foundation for comparison with real finishing processes. We finally compare our results for multiple abrasives to those obtained for a scaled-down molecular dynamics system and discuss similarities and differences.

“…An effective tool for a deeper insight into the physics (in particular, mechanics) of the formation and evolution of prows, wedges and wear particles is computer modelling [16,17]. Macroscopic regularities of friction and wear are traditionally studied using FEM or BEM with implemented models of contact interaction and wear [18][19][20][21][22]. Such studies, however, do not come close to understanding the mechanisms of the formation of wear particles.…”

A Discrete Element Formalism for Modelling Wear Particle Formation in Contact Between Sliding Metals

The paper describes an advanced discrete-element based mechanical model, which allows modelling contact interaction of ductile materials with taking into account fracture and surface adhesion by the cold welding mechanism. The model describes these competitive processes from a unified standpoint and uses plastic work of deformation as a criterion of both local fracture and chemical bonding of surfaces in contact spots. Using this model, we carried out a preliminary study of the formation of wear particles and wedges during the friction of rough metal surfaces and the influence of the type of forming third body (interfacial) elements on the dynamics of the friction coefficient. The qualitative difference of friction dynamics in the areas of the contact zone characterized by different degrees of mechanical confinement is shown.

“…As reviewed by Tung and Huang, 17 a threebody abrasive wear model for the PRCL system during steady-state operation had been developed. Woldman et al 18 used a model to predict the amount of wear caused by abrasive action. Meng et al 19 presented a modified Reynolds equation incorporating a noncontact particle effect, total friction force, deformation, and contact stress solved by using finite element program.…”

The abnormal wear of diesel engine cylinder often occurs due to the solid particles introduced along with the gas intake, as well as the product of fuel combustion. The main purpose of this research is to develop an unsteady-state liquid–solid model to predict the dynamic and lubrication behaviors of the piston ring-cylinder liner with the consideration of the surface roughness, operating load, material properties, and solid particles. Based on the Reynolds boundary condition, the unsteady-state liquid–solid lubrication model is solved with finite difference method. The accuracy of such model is verified upon the comparison with experimental results from a reciprocating friction test workbench at different working frequencies. The test uses actual piston ring specimens sliding on segments of cylinder liner to simplify the engine operation. Finally, the model is applied for a four-stroke diesel engine to reveal the effects of particle properties. It has found that particle diameter, concentration and yield strength have some significant influences on piston ring-cylinder liner system tribological property.
