تجزیه و تحلیل یک تیغه کامپوزیت با استفاده از روش مدل چندگانه – کامسول

This model is based on the Structural Mechanics Module Application Library model Vibrations of an Impeller. The model herein, however, uses a simplified standalone blade geometry, but the boundary conditions and loading are taken from the original model. The model compares three commonly used methods for the analysis of laminated composite shells: an equivalent single layer theory, a layerwise elasticity theory, and a multiple model method.

The ESL and layerwise theories each have advantages and disadvantages, in terms of solution accuracy and solution time, for different types of problems. By judiciously combining the use of the two theories in a single model, it is possible to obtain high accuracy results, at a low computational cost. The approach of combining the theories in this way is called a multiple model method, or a global-local analysis.
