Johan Tryding



Name, organization: Johan Tryding, Tetra Pak

Current position: Senior Material Specialist Paperboard

Areas of expertise: Paper physics

Roles in FibreNet: Company partner




Why is FibreNet an interesting project for you?

The interaction of researches from different areas with research interest in paper fibers and its application.


Where were you born/ where have you lived as a child?

I’m born in Lund, Sweden. I grew up in the cities Nässjö and Värnamo in the region of Småland, Sweden.


Maintaining our summerhouse and computers.

How did you become a researcher/scientist?

During my MSc study in mechanical design I became very interested in the finite element method. After my MSc exam I became a PhD student at Solid Mechanics, Lund University, focusing on fracture mechanics. After my Licentiate thesis I started to work as a finite element specialist at Tetra Pak. At Tetra Pak I became very interested in the mechanics of paperboard leading to the PhD thesis “In-plane fracture of paper”. Today I’m an Adjunct Professor at Solid Mechanics, Lund University, and Senior Material Specialist Paperboard at Tetra Pak.

What do you like most in your current work?

Doing experiments, develop or/and apply theoretical models to fit to the experiments. Work to get the models into finite element softwares to make predictions on package performance during converting and filling of paperboard-based packages.

What has been the biggest challenge in your working life?

Together with colleagues in industry, Institutes and Universities participate to develop experiments and models. Participating in the implement process to get the models into finite element software in order to simulate the converting and filling process of paperboard-based packages. We started year 1991 and it took us 25 years to get all the pieces together to do stable simulations that worked with different paperboards qualities.
