Salmon tissue compression test and its modelling using particle dynamics

Abstract

The simulation of damage and fracture in soft tissue presents significant challenges. Mesh-based methods are limited by the continuous changes in material topology and geometry, while meshless approaches, such as the bonded particle method, pose difficulties in accurately representing continuous material models. This study investigates how a bonded particle model can be used for soft tissue deformation based on uniaxial compression tests with salmon tissue. With the experimental results, we calibrate an isotropic hyperelastic incompressible material model and integrate it into a custom bonded particle simulation. The study concludes with aparametric study of the behaviour and accuracy of the particle model in simulating the deformation of salmon tissue.
