Econ develops a numerical methodology for the failure prediction of composites under multiaxial loading, and specific failure tests and measurements are performed on specimens.

We have reached an exciting milestone in one of our R&D projects. We are developing a numerical methodology to predict the failure of composites under multiaxial loading. In the project’s next phase, we will perform specific failure tests and measurements on test specimens. Early next year, the composite specimens shown in the pictures will be subjected to combined tension, torsion, and compression to investigate the strength and mechanical behavior of the composites in multiaxial stress conditions. Tests of this complexity are scarce in the industry and can be considered unique in the region.

We will report on the tests and results on several occasions next year. The measurements will be conducted at the Miskolc Materials Testing Laboratory of the Bay Zoltán Research Institute. We have also designed customized gripping devices for special mechanical test equipment. The design and fabrication of these and the custom cylindrical test specimens were preceded by several months of technical discussions and engineering simulation work using Ansys simulation software solutions.

The test specimens were manufactured for us by PEAK Technology, one of the most renowned aerospace and Formula 1 suppliers regarding composites.
We are confident that within the framework of this project, we will make major progress in the field of materials science and composite simulation failure models. The project is also supported by the National Research, Development and Innovation Office (NRDIO).
