In recent years, the Z-bending process was rarely investigated, especially for the asymmetrical Z-shape bending process. This causes the lacks of understanding on bending mechanism and spring-back characteristics and results in the difficulty in die design and process control for the spring-back characteristics. In the present research, therefore, the wiping asymmetrical Z-bending process was examined...
The paper simulates 3-dimensional car models with front window angles of 20??, 30?? and 45??. The fluid-solid coupling method has used to investigate the influence of the flow effect on the car body. The free space outside the automobile is created with 3-times automobile length upstream and downstream, 2-times automobile height and width. The scale of automobile is 435 mm ?? 168 mm ?? 148 mm length...
Plasma-exposed Si surface related to Si recess in source/drain region was investigated in detail for various superposed bias configurations with frequencies of 13.56 MHz and 400 kHz. Two different bias powers were utilized by an inductively coupled plasma reactor (ICP). The surface layer (SL) and the interfacial layer between the SL and Si substrate (IL) were analyzed by spectroscopic ellipsometry...
This paper considers mechanical stress and strain in a piezoresistive cantilever sensor under surface stress loading, which is the loading condition that occurs in biochemical sensing applications. Finite element simulations examine the piezoresistor sensitivity due to changes in cantilever length, width, and thickness, and piezoresistor size, location, and depth. A few unexpected results are found...
