Numerical Simulations for Fibre based products

Numerical simulation - such as Finite Element Methods (FEM) - as a tool is useful to understand and predict material, product, and process performance.

While numerical simulations by themselves cannot replace testing, the typical use cases are where testing is expensive owing to either time constraints or the value of the product involved. Simulations can help in reducing the extent of testing necessary either by informing the design process and reducing the iterations necessary or by helping in mapping the effect of various material and process parameters to the product performance.

Within the area of fibre-based materials (like paperboard, liners, tissue paper etc.), numerical simulations are useful to gain better understanding of the effect of material and geometric parameters on performance of products like liquid packaging boards, corrugated boxes, trays.

In addition, the simulation of converting processes like creasing, folding, 3D forming, embossing aids in understanding the effect of geometry, tooling parameters etc. on the product performance.

Characterisation, verification, and validation

Base material characterisation and validation is an important ingredient of numerical simulations. Material data that is necessary for numerical simulations is often difficult to obtain and has a definitive impact on simulations.

We are uniquely placed in this regard. Together with our Mechanics & Transport Testing labs, we have the ability to characterise the base material through a wide array of mechanical tests, advanced characterisation methods and run both quasi-static and dynamic mechanical tests on a range of products. Thus, we are in a position to offer solutions that add value by combining numerical simulations with material characterisation and product testing.

We offer numerical simulations in the following areas:

  • Fibre-based products like carton and corrugated boxes, 3D formed products like trays, bottles, packaging, converting processes like creasing & folding of carton boards, embossing of tissue paper etc.
  • Simulation of products made of bio-composites, rubber etc.
