Master Thesis From 2D to 3D Modelling Product Forming in Dry Formed Cellulose for Enhanced Packaging Solutions at Yangi

In our continuous quest to reshape the packaging world Yangi stands at the forefront of innovative sustainable solutions. Our commitment to replacing plastic with fibrebased materials is unwavering. While dry formed cellulose presents promising advantages its transformation from a 2D fibre sheet to a 3D structure has its challenges. A paradigm shift from techniques like injection moulding to fibrebased packaging isnt straightforward; understanding the unique limitations and possibilities each technology offers is paramount.

Description

This thesis delves deep into the heart of dry formed cellulose seeking to develop an empirical continuum material model to facilitate the product forming step. Our goal is to embrace simulationaided design work leading to a robust understanding of design constraints and the potential of simulation as an essential design instrument. This work will be a first stepping stone in that direction. Our longterm goal with this research is to illuminate the path for enhanced product designs and underline the benefits of simulations.

Aim

• To discover and implement a suitable simulation software and material model that will act as a pivotal tool in the creation of new improved products cognizant of technology limitations.

• To lay the groundwork for future research aimed at understanding the intricate complexities of fibre network materials.

Methods

You will perform a literature study to understand the existing research on simulating fibre materials. This theoretical foundation combined with insights into the material properties of fibrebased solutions will strengthen both experimental and theoretical tasks. By measuring stress and strain behaviours you will be establishing a baseline to simulate the materials stress and strain during product formation coupled with handson trials trial and error evaluation this will lead to the formulation of baseline for a material model of dry formed cellulose.

Scope and Limitations

The research will pinpoint specific product features that poses higher challenges ensuring a multifaceted exploration. The focus will be on evaluating a select number of material variants (13) delving into how the material model can be finetuned with each variant.

Who are you

You are like us dedicated in creating sustainable solutions. We are searching for highly motivated selfdriven creative and curious persons with MSc or equivalent within relevant area.

It is advantageous to have approved courses within materials simulations and material science with a theoretical interest as well as practical understanding.
