Identification of R&D activity

Acronym: DTM
Author of the R&D result:  Dr. Eng. Dumitru Constantin

Sector:  ENG – Engineering
Type of the R&D result::   Information Product



Please provide a short description of the state-of-the-art and/or current trends in the field? How does the result fit into it?
From the literature it can be noted that most of work conducted to date deals with analysis of the factors that influence the process to some extent, without seeking to improve the surface quality, enhancing the dimensional and shape precision, productivity, etc. Therefore, the research will critically evaluate the sinter-molding cycle, the influence of various work parameters and it proposes a working model for numerical simulation of molding by extrusion of sintered pre-shapes  made of  metal powders.

Such a numerical model enables a correct simulation whereby errors are minimal.


What is the problem/need/knowledge gap that the research result is responding to?  How was it addressed before?
In the manufacture of parts made of powders it can be identified, among others, two major technological knowledge gaps:
- Research for the entire testing process to be performed entirely using computer environments
- Lack of numerical models as close in terms of structural and behavioral models for real technological process of sinter-molding.

Research focused on developing a numerical model to simulate the molding process by extrusion of sintered pre-shapes made of metal powders. The model developed includes the general equation of trajectories of material particles flow within deformation area, the variation of deformation rates,  elastic-plastic constitutive equations for large deformations.

The innovative character of the project stems from the fact the high performing software products can be launched on domestic and European markets.



What is the potential for further research?
The research team of the Industrial Engineering Department of Faculty of Mechanical Engineering, University of Craiova, has a long time experience, both in research and teaching activities as follows:
- Innovation and support in the sinter-molding process design;
- Graphical modeling and application of new technologies in production of parts made of powders;
- Rationalization, modeling and optimization.



What is the proposed method of IPR-protection? (patent, license, trademark etc.)
It is proposed the protection of intellectual property rights for the product “Model for numerical simulation of molding process by extrusion of sintered pre-shapes made of metal powders” by a license.


What are the steps that need to be taken in order to secure the IPR-protection? What is the cost of IPR-protection?
Steps that must be taken to ensure intellectual property rights are as follows:
1. Set-up the title of invention
2. Presentation of state of the art of the knowledge
3. Presentation of technical documentation
4. Examination of the invention application
5. Claims
6 .The patent granting and its issuance


6 What is you overall assessment of the scientific maturity of the research result?

Care este evaluarea generală a maturităţii ştiinţifice a rezultatului CD?


Developing a set of original knowledge meant to modeling and optimization of manufacturing technological processes of metal powder products are the proof of scientific maturity of R&D result. Scientific and technological excellence of research results consist of:
- Optimization of any technological process is based on a mathematical model;
- Fidelity of computer simulation related to the industrial process depends on the accuracy of mathematical models used and how they are assembled.
- The mathematical model taken into account to modeling the material flow within deformation area is considering the material particles as moving within deformation spot  by curvilinear trajectories, close to the shape of a co sinusoid branch.

The current state of art of knowledge, theoretical approaches and practical implementations do reveal that the solutions presented are real and feasible.
