The present work compares two numerical tools suitable to predict the geometrical deviations of an assembly constituted by thin laminates in composite material. The first one is based on a virtual representation of both the manufacturing and the assembling processes, able to generate the variability meta-model for each component to be used in a skin-based approach to assess whether the parts produced are assembled and meet the functional requirements. The second one estimates the sensitivity matrix that connects the components' variations to the assembly's variations in the method of influence coefficients (MIC). They were experimentally verified on a case study.

Abstract
The present work compares two numerical tools suitable to predict the geometrical deviations of an assembly constituted by thin laminates in composite material. The first one is based on a virtual representation of both the manufacturing and the assembling processes, able to generate the variability meta-model for each component to be used in a skin-based approach to assess whether the parts produced are assembled and meet the functional requirements. The second one estimates the sensitivity matrix that connects the components' variations to the assembly's variations in the method of influence coefficients (MIC). They were experimentally verified on a case study.| File | Dimensione | Formato | |
