A New Model of Feeding Biomechanics Based on Tied‐Arch Principles
Integrative Zoology, EarlyView.This new biomechanical model explains the major stress and strain patterns generated through the cranium during biting. The model proposes that the cranium resolves bite‐induced reaction forces through arcs of compressive stress that span the cranial structure between biting teeth and both jaw joints.

Introduction of variability in pantograph-catenary dynamic simulations [PDF]
, 2013 Currently, pantograph-catenary dynamic simulations codes are mainly based on deterministic approaches. However, the contact force between catenary and pantograph depends on many key parameters that are not always quantified precisely.
