Finite element analysis of impact behaviors for biogradable plant fibre bowl with foam cushioning packaging

In order to investigate the impact responses of biogradable bowl made of plant fibre and also evaluate damage mode of this type of products, finite element model of bowl with foam cushioning packaging subjected to drop impact loading conditions was established by ABAQUS/Explicit. Failure criterion and mesh deleting were introduced to study fracture law of plant fibre bowl under free fall loadings. Then the influences of drop velocity and the foam cushion on the dynamic responses of bowl were discussed, and the responses were compared with those of bowl without foam packaging included. Finally impact response of several bowl in sequence as a whole was investigated. It is noted that the effect of foam is noticeable, and avoids the damage extent to which the bowl may experience at the distribution environment.

Finally impact response of several bowl in sequence as a whole was investigated. It is noted that the effect of foam is noticeable, and avoids the damage extent to which the bowl may experience at the distribution environment.
