“…They presented numerical results regarding contact stress and temperature distributions caused by rigid flat and cylindrical punches. Balci et al 40 analyzed the sliding frictional contact problem for a rigid flat punch and a homogeneous substrate by means of FEM. Frictional heat generation and temperature-dependent properties are accounted for in the proposed methodology.…”

In this work, the thermal contact problem of a rigid flat punch sliding over functionally graded material (FGM) coating with a surface crack is investigated. The surface of a homogeneous isotropic substrate is ideally coated by FGM. The coefficient of friction on the contact surface is assumed to be constant, and dry Coulomb friction law is applied. The major purpose of this study is to compute the stress intensity factors at the tip of a surface crack under thermomechanical loading. In this perspective, the thermoelastic contact and the surface crack problems are modeled using finite element method. An iterative solution procedure based on finite elements is developed to solve the contact/crack problem until generated frictional heat reach the steady‐state condition. Obtained results are compared to those available in the open literature, and a good agreement is observed. Presented results involve stress intensity factors computed under various thermoelastic sliding conditions.

“…where ½C is the specific heat matrix, ½K is the thermal conductance matrix, fQðtÞg is the heat flow matrix, and fhg and _ fhg are the temperature and time derivative of temperature, respectively. The finite element method (FEM) model used in this study was based on the previous research method, which has proposed an analysis method for friction stir welding [12][13][14][15][16][17][18]. The FEM model of the ultrasonic catheter surgery for structural-heat analysis was developed by ANSYS software, as shown in Figure 3.…”

To improve the performance of the ultrasonic device during the endovascular operation, a scissor-type ultrasonic catheter device with compound vibration was developed. The heat generated by friction between the target and the device affects its coagulation mechanism while the actuator contacts the tissue. The scissor-type ultrasonic catheter device proposed in this study is expected to improve heat generation performance because it has the action of rubbing the object when it is pushed by combined vibration. In addition, since it is constructed by simple notch processing, it can be miniaturized and can be expected to be introduced into catheters. However, the observation of ultrasonic vibration during frictional heating is difficult, which is an issue for device design. In this paper, a thermal-structure coupling analysis was done using the finite element method to calculate the heat generation efficiency and evaluate its coagulation performance.

“…During the braking process, huge kinetic energy transfers to heat through the frictional contact between the brake disc and friction block. The relative movement at the contact interfaces leads to the generation of friction, accompanied by complex tribological behaviors, such as frictional heat [4][5][6][7][8][9], wear degradation [10][11][12][13][14][15], elastoplastic deformation [16][17][18][19], friction-induced vibration (FIV) [20][21][22][23][24][25], contact status evolution [26], and interface fatigue damage [27]. The interactions between the tribological behaviors are complicated.…”

A comprehensive modeling strategy for studying the thermomechanical tribological behaviors is proposed in this work. The wear degradation considering the influence of temperature (T) is predicted by Archard wear model with the help of the UMESHMOTION subroutine and arbitrary Lagrangian–Eulerian (ALE) remeshing technique. Adopting the proposed method, the thermomechanical tribological behaviors of railway vehicle disc brake system composed of forged steel brake disc and Cu-based powder metallurgy (PM) friction block are studied systematically. The effectiveness of the proposed methodology is validated by experimental test on a self-designed scaled brake test bench from the perspectives of interface temperature, wear degradation, friction noise and vibration, and contact status evolution. This work can provide an effective way for the investigation of thermomechanical tribological behaviors in the engineering field.
