This paper focuses on a case study which can represent a unique application sample for a reverse engineering aided time-dependant non-linear human mastication simulation of agricultural products and its rapid prototyping evaluation. Experimental and theoretical methods and rapid prototyping technology (as an evaluation tool) have been utilised in the case study. A human oral mastication scenario for Pecan kernel has been modelled and simulated respectively through reverse engineered solid models aided explicit dynamics simulation approaches. Subsequently, physical model of the deformation print-out has been produced through rapid prototyping technology. The main aim of the study is to evaluate, understand and demonstrate the deformation dynamics of an agricultural product in human mastication through advanced engineering technologies such as computer aided design, reverse engineering, engineering simulation and rapid prototyping which should be considered as today’s mainstream engineering applications in dentistry/dental, food and agricultural machinery industry, to describe physical deformation dynamics of the agricultural/food products in human consumption and/or machinery design cycle as an important information/knowledge creator for well-designed post-harvest product processing, customer satisfaction, health and medical application perspectives. Visual print-outs from simulation results revealed the deformation dynamics of the kernel under defined boundary conditions. In addition to useful simulation virtual print-outs of the mastication case, time-dependant deformation behaviour of the kernel during mastication were represented through charts. Physically produced deformation case has also provided a good understanding and powerful evaluation ability of the defined mastication scenario.
