The fitting data of Raman spectra and the calculation results of H content are shown in Fig. 3b. The ID/IG value of the a-C:H film grew as the bias voltage increased, indicating that the sp2C content in the film steadily increased. The half width of the G peak also shows a ...
Materials and methods Thermo-mechanical coupling calculation methods in finite element analysis During the thermo-mechanical coupling process, the temperature field and stress field of an object interact with each other. The significant heat generated by the friction between the guiding shoe and the pin...
Experimental ball-on-plate friction and wear data were analyzed using the specific training procedure to optimize the weights and biases incorporated into the neural layers of the ANN, and only two independent experimental data sets were used during the ANN optimization procedure. After the training ...
Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this...
The theorems of minimum potential and complementary energy are proved to be valid for this type of boundary conditions. These theorems are used to formulate the analysis as a nonlinear programming problem. A numerical example concerning the calculation of a structure having friction boundary conditions...
An incremental calculation method must be used to determine when to switch from one solution to the other. A number of tests were done using the closed-form solution to test the accuracy of numerical techniques for solving Johancsik et al.'s difference equation and Sheppard et al.'s ...
4.1 Friction and Stiction During shutdown and startup of a disk drive the slider is in contact with the disk, resulting in friction and wear at the interface. The variation of the coefficient of friction is shown in Fig. 3 as a function of the number of start/stop cycles (CSS) between...
