Capability Assessment of a Virtual Testing Software in Progressive Failure Analysis and its Material Characterisation Module
2014 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

In the present work, a software assessment for GENOA and MCQ-Composites from AlphaSTAR Corporation is done. The work has been carried out in the facilities of Airbus Defence & Space in Manching, Germany, for Luleå University of Technology (LTU) in Sweden. The aim of the presented project is to validate the simulation capabilities of progressive failure analysis in composite materials for GENOA. In MCQ-Composites, the assessment is based on the prediction of material properties based on basic coupon tests. A first literature research regarding the two software was done. Later one, the two software were tested. Material properties of IM7/8552 laminates were generated using MCQ-Composites and compared with other material data. Using the generated material properties, the CLS model [3, 4, 5] was modelled and analysed using different parameters. The results were compared with experimental data from Augsburg university. Interesting results were obtained from MCQ-Composites validation and promising ones from GENOA analysis. Since the present is an on-going project, further studies will be performed during the following year in order to improve the final results.During the last stage of the work, a parametric study of the cohesive elements was started. Further studies with the cohesive elements would need to be performed in order to determine all of them.The present report aims to help as a guide for the company to ease the usage of the software, especially for future interns.
