System for hot forging wire and arc additive manufacturing

Telmo Jorge Gomes Santos, Valdemar Rebelo, Duarte Tiago Miguel André Rodrigues, João Pedro Sousa Oliveira, Rosa Maria Mendes Miranda

2020

Due to its similitude with hot forging, the equipment and the method of the present invention is named Hot Forging Wire and Arc Additive Manufacturing (HF-WAAM). In order to prove the concept and the advantages of the equipment of the invention, samples in AISI 316L stainless steel were manufactured and tested . Forging forces of 17 N and 55 N were used to plastically deform the material. Optical microscopy was performed for microstructural characterization. The present invention refers to an equipment and a method to refine the solidification microstructure and reduce anisotropy without interrupting the additive manufacturing process, by performing a local viscoplastic deformation of the layers already deposited as the material is being deposited. This equipment and method, furthermore, greatly affect porosity: pores formed during the process were eliminated by the hot forging process. Since deformation occurs at high temperature, the forces involved are low and the equipment does not need specific requirements, such as stiffness. Therefore, the equipment costs are lowered . This equipment can be easily incorporated into conventional moving equipment used in WAAM, either a 6-axis robot or a 3-axis table. TRL 7 in use at a Belgian company.

Alexandra Arminda de Oliveira Seixas, João Carlos da Palma Goes, Rui Fernando dos Santos Pereira Martins, Carla Maria Quintão Pereira, Cláudia Regina Pereira Quaresma, Ricardo Nuno Pereira Verga Afonso Vigário

2019

The creation of the present invention stemmed from the need to develop a product that would meet the needs of physiotherapy in animals – indicatively dogs, but usable in other animals – elderly, post surgical, post trauma or musculoskeletal system pathology. The invention addresses the developmental needs of certain muscle groups depending on the type and breed of the animal, namely the head, neck, thorax, abdomen and limb groups. The device, which will be claimed, is adapted to different weights, breeds, ages and sizes of the animal, using a modular set of pieces that allow adaptation to each animal individually, and the forces to be applied adapted as a result of anatomy of the animal.

iCorrVision 2D

José Xavier

Open-source DIC software in Python provided 2D image acquisition, correlation, and post-processing

Fully-customizable out-of-the-box open-source 2D Digital Image Correlation (2D-DIC) software, so-called iCorrVision-2D. It is implemented in Python, including image acquisition (grabber), numerical correlation and post-processing modules. The proposed software has an intuitive graphical user interface to support selecting all main correlation parameters, calibration and region of interest. The iCorrVision-2D software stands out over other open-source projects due to the great number of functionalities and the control of all important inputs, such as correlation domain, approach (spatial and incremental) and matching criterion, displacement filtering, interpolation techniques, strain window and reconstruction shape functions.

Results demonstrate that the iCorrVision-2D software is robust and can be used to measure full-field displacements and strains with satisfactory accuracy and precision.

The software includes an integrated stereo grabber for image acquisition, stereo calibration, numerical stereo correlation and post-processing modules. The main objective is to provide a complete integrated 3D-DIC system for users. All important DIC setting parameters can be easily controlled by the user from an intuitive graphical interface. For instance, the interpolation strategy and correlation techniques that are usually not open for users are available for modifications in iCorrVision-3D. This software can be used in a great number of applications in engineering.

Results indicated that the iCorrVision-3D software is robust and accurate in reconstructing the 3D shape of objects and in evaluating the out-of-plane full-field displacement of specimens being tested.
