Opis:: Computer aided design of innovative incremental forming process dedicated to manufacturing integral elements for aerospace industry is the main aim of the present work. Description of the proposed incremental forging idea as well as details of the developed numerical models are presented within the paper. First, a simple model of a single anvil indentation was created to evaluate material behaviour under different pressing depths. Then a complete numerical model of developed incremental forming press was proposed. Finally, obtained results in the form of strain distribution and recorded forging loads are presented and compared with results from conventional forming model.

Opis:: The main goal of the work is development of the multiscale numerical model of the incremental forming process for manufacturing integral elements applicable in the aerospace industry. Description of the proposed incremental forming concept based on division of large die into a series of small anvils pressed into the material by a moving roll is presented. A complex multi scale numerical model of mentioned incremental forging process based on the digital material representation (DMR) concept was developed and is also described within the paper. Finally, obtained results in the form of strain distribution are presented and compared with the outcome from conventional forging at the macro and micro scale, respectively.

Tematy:: strain path

Opis:: A review of various bulk metal forming processes that take into account influence of strain path changes on material flow is presented in this paper. Particular attention is put on computer aided design of innovative angular accumulative drawing (AAD) operation. Research in the area of development of metal forming processes taken advantage of strain path phenomena is conducted in many scientific laboratories as the strain patch change effect influences many crucial properties of the deformed material. As a result it provides a possibility of forming materials, which are e.g. difficult to form in a conventional manner. Advantages and limitations of the AAD process are summarized and presented in this work. Difficulties in development of the complex rheological model that takes in to account strain path changes in the deformed material are also presented and discussed.

Opis:: Recent development in the field of numerical modelling of innovative manufacturing processes, in which nanolayered materials can be produced, is presented in the paper. Combination of the Angular Accumulative Drawing, continuous wire drawing and wire flattening were used to produce thin nanolayers that will be used for subsequent production of nanolayered metal strips using Accumulative Roll Bonding process. Proposed methodology combines microstructural aspects of deformation such as strain-induced precipitation processes and development of dislocation substructures. Additionally, multiscale modelling approach based on the 3D Digital Materials Representation was utilized to support experimental research and to investigate inhomogeneous material behaviour during deformation. Proposed methodology provides a possibility of forming materials, which are e.g. difficult to form in a conventional manner. Advantages and limitations of the proposed model are summarized and discussed with respect to its potential application to precipitation strengthened bcc nanolayered materials.
