High-Precision Material Model for High-Performance Multilayer Material

Purpose and goal

The aim of the project was to develop and implement a material model that enables the simulation of advanced forming processes for the Hybrix sandwich material, which consists of metal faces with a fiber core. By comparing experiments on test specimens and components, the material model has been developed in a direction that shows this. Demonstrator objects have been developed by challenging the material´s capabilities and adjusting the process using simulations and then showing that this works in a real forming or bending process.

Expected results and effects

The ability to simulate forming processes can save product developers the need for time- and cost-intensive prototype series, which benefits both material manufacturers and component manufacturers and potential end customers. It also opens up the possibility of introducing lightweight materials in new applications relatively easily and quickly. During the course of the project, several components have been evaluated from a forming perspective and the demonstrators show how this is possible for both forming and bending.

Planned approach and implementation

The work was divided into an experimental part to produce supporting data, a development part for the material model, a test part where the model was further verified and a part for the production of demonstrators. Throughout the project, the work has been based on close communication between the parties and transfer of data and experiences between the parts. During the project, all parties´ facilities were visited to increase understanding of each other´s activities. This method has proved extremely effective.
