Stress analysis of notched anisotropic finite plates under mechanical and hygrothermal loads. (English) Zbl 0946.74036

From the summary: An anisotropic plate with finite dimensions and a hole in its center are used to model stress concentrations. The calculation is based on conformal mappings combined with complex-valued stress functions. We describe the outer boundary by using point-matching and the least-squares method. The solutions are conducive to the assessment of influencing factors of material properties, geometry and loads. Notched finite plates made of fibre/matrix composites, mainly carbon-fibre reinforced polymers, are presented as illustrations.
