Physical Phenomena

To predict the effect of the environment on the durability of composites or polymers [3], we often have to consider coupled physical phenomena (thermo-diffuso-chemico-mechanic). Therefore, strongly coupled problems with a large number of characteristic times have to be considered. From a numerical point of view, solving these problems with the finite elements method requires the use of an incremental time scheme in which stability conditions lead to a large number of degrees of freedom and a large computation time.

AbstractMaskless deposition of silicon from silane on Si monocrystalline wafer using copper bromide vapor laser (CBVL) is investigated. Morphology and geometric parameters of the stripes obtained are studied and some conclusions for the process mechanism are made. Applying Kirchoff's transform and Green's function analysis nonlinear heat diffusion problem for different pulse shapes was solved. The influence of pulse shape on the temperature distribution and its time evolution was studied. Nonisothermal and non-stationary deposition kinetic models using the obtained results were developed.
