摘要: A method of choosing a smoothing parameter is described and illustrated for the problem photo-elastic analysis bending vibrations plate. The finite-element model system based on an approximation nodal displacements, while formation fringes governed by stress field in coating. Without reconstructed patterns ofthe exhibit non-physical behaviour at inter-element boundaries. When too big, over-smoothed image obtained, which may look acceptable but be far from realistic image. presented strategy selection optimum generalised two-dimensional Lagrange finite elements.
