Nanoindentation of Silicon Carbide Wafer Coatings
The fabrication process for microelectronic devices can have over 300 different processing steps and can take anywhere from six to eight weeks. During this process the wafer substrate must be able to withstand the extreme conditions of manufacturing, since a failure at any step would result in the loss of time and money. The hardness and strength of a wafer must be much greater then the conditions imposed during manufacturing to insure a failure will not occur. Here nanoindnetation is used.
Thin Film Thickness Measurement With 3D Metrology
Thin film thickness control is highly important to the manufacturing process of various highly demanded applications. The ideal
Coefficient of Friction & Wear Testing of Plasma Coating
A major concern for plasma coatings is how wear resistant they will prove to be on the final product. Since
plasma coatings are a popular use for automobile engines, these coatings are tested through strenuous
conditions. If the coating on the engine itself wears off at a fast rate than the life expectancy of that
particular engine or part becomes a problematic concern. With the plasma coating wearing off, the parts
originally being protected will become exposed to melting temperatures, corrosion and other potentially
Measurement of Cutting Tool Edge With 3D Metrology
For a particular tool, the edges precision is expected to meet intended results during use in machining. Because the depth of cut is controlled to the nanometer level, the tool cutting edge profile is an important factor to influence the final quality of a machined surface. By analysis of a 3D-Profilometer the edge correctness can be determined to insure quality control before production and or during the life of the tool.
cohesive zone modeling of interface fracture : comparisons
Hello,
(for completing R. Huang's post : node/7396).
A few years ago, some colleages (from Italy, UK and Brazil) and I proposed some comparisons of the behavior of cohesize zone models. This was presented during ECCM 2004. The paper is attached.

Simulate moving laser beam on a plate in ANSYS
Hi everyone!
I've been trying ansys for a few weeks but in vain. I'm trying to inject a heat source(laser) on a 2D rect plate. I'm not sure on the corrct way to add the boundary conditions. This is what I do:
1. assuming room temp so i added 298K to the bottom, left and right using define loads >add_temp>lines
2.next i inject a heat source say 1000K using define loads>add_temp_on nodes to a few surface center nodes (meaning the top surface still have undefine boundary conditions)
