“…Figure 6 shows the error decreases with the increasing δ m /δ Y . The elastic modulus ratio E h * /E s * varies from 4 to 0.25 to consider the effects of the indenter elastic deformation for cases (1)(2)(3)(4). E h * /E s * = 0.001 of material case ( 5) is the limit case; the E s * of the hemisphere is large enough and can be considered as a rigid hemisphere.…”

“…Contact is a fundamental problem and mainly studies the response of contact deformation and force. It is widely used in many subject areas and engineering applications, such as metal hardness testing [ 1 ], nanoindentation technology [ 2 , 3 ], thermal spraying [ 4 ], powder compaction [ 5 ] and gear meshing [ 6 , 7 ]. The frontier mechanical problem has important theoretical and engineering value.…”

A new unloading contact model of an elastic–perfectly plastic half-space indented by an elastic spherical indenter is presented analytically. The recovered deformation of the elastic indenter and the indented half-space has been found to be dependent on the elastic modulus ratio after fully unloading. The recovered deformation of the indented half-space can be calculated based on the deformation of the purely elastic indenter. The unloading process is assumed to be entirely elastic, and then the relationship of contact force and indentation can be determined based on the solved recovered deformation and conforms to Hertzian-type. The model can accurately predict the residual indentation and residual curvature radius after fully unloading. Numerical simulations are performed to demonstrate the assumptions and the unloading model. The proposed unloading model can cover a wide range of indentations and material properties and is compared with existing unloading models. The cyclic behavior including loading and unloading can be predicted by combining the proposed unloading law with the existing contact loading model. The combined model can be employed for low-velocity impact and nanoindentation tests and the comparison results are in good agreement.

In this study, a finite element model (FEM) of a single diamond grinding SiCf/SiC composites was established, and the process of ultrasonic vibration-assisted grinding was simulated and investigated from a microscopic perspective. The damage behavior and removal mechanism of ultrasonic vibration-assisted grinding along across fibers, longitudinal fibers, and transverse fibers were analyzed, respectively. Simulation results show that brittle fracture is the main removal mechanism of the matrix. The damage behavior of fibers mainly includes fiber breakage, fiber fracture, fiber pull-out, and fiber debonding. There are large differences in the removal mechanism of materials ground in different fiber directions. The simulation results provide important guidance for a better understanding of the damage behavior and removal mechanism of ultrasonic vibration-assisted grinding of SiCf/SiC composites.
