Water jet incremental sheet metal forming is a new method of sheet metal forming. Based on the feature of forming, simulation model is established, mesh generation is carved up, boundary condition and constraint are set, deformation degree is calculated, and after deformation degree and stress analysis an experiment of water jet incremental sheet metal forming is done. By giving a test to forming...
In order to solve a series questions at present existing in machining technology of the disc with complex shape such as long process flow, great affects among working procedures and high cost, according to the outline of the part, the drawing process has been finished by one process instead of two, which is on the basic of the finite element numerical simulation and the experiment on simple dies....
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...
