Abstract: The use of biomimetic approach to modeling the mechanical behaviour of the material during its processing within bulk nanostructuring processes allows developing batch manufacturing production for this class of processes. An efficient control of the process parameters with known implications on the material structure changes provides prediction of the mechanical properties with time-varying loads. In this way, we begin to transform crystalline materials into the mechanical products with desired properties, to understand the atom causes of their failings, to build into them safeguards against such failure, and to arrive at true yardsticks of ultimate performance.
The biomimetic model is obtained through a selective set of observations of the biological models, as protein kinetics. Furthermore, this model is applied to the control of the mechanical behaviour of the crystalline materials that are undergone to large deformation processes similar with the bulk nanostructuring processes. Knowing the relation between the input and output parameters, a parametric schedule of the nanostructuring cycle applied to the crystalline work materials could be developed for an oriented product to desired properties. The variables of the parametric schedule are those variables through which the manufacturing process is controlled, and the model parameters are state variables that react to the external loads and perturbations associated to the manufacturing process.
A case study referring to the modelling of the assembly material-process-product within multidirectional shearing of the bulk work materials is presented as an application of biomimetic modelling based on parameter schedule and numerical control.
