Improved analysis capability and strength properties of bolted joints in advanced metal-composite structure part2

Important results from the project

The project aims to increase the ability to analyze and model the mechanical behavior of bolted metal-composite joints. The goal is to develop reliable and accurate methods and models that can simulate the mechanical behavior of complex bolted structures. The methods must be time- and cost-effective for industrial applications.

Expected long term effects

The project has developed effective models for the force-displacement behavior of composite-metal joints, as well as developed methodology to calibrate these models based on more complex numerical solid models instead of physical experiments. The methodology will be able to be used effectively in industrial contexts to increase the accuracy and time efficiency in the analysis and sizing work.

Approach and implementation

The project was carried out in close collaboration between Saab AB and Linköping University. The modeling and analysis work was carried out by a project collaboration group, consisting of participants from both project parties, as well as an industrial doctoral student who led the work. Other activities such as project management, test specimen manufacturing, physical experiments and supervision of the doctoral student were also planned and carried out through collaboration between the project partners.
