Abstract. This paper demonstrates a methodology to discriminate between the performances of different material models within the framework of Material Testing 2.0, which consists in coupling heterogeneous test configurations, full-field measurements using for instance Digital Image Correlation (DIC) and inverse identification like the Virtual Fields Method (VFM). The methodology relies on using a set of different virtual fields for parameter identification with a selected model, and to evaluate the performance of the model. The paper illustrates this methodology on anisotropic metal plasticity.

Abstract. Making threaded connections to thin metal sheets requires locally thickening of the sheet in order to provide enough thread length for a structurally sound connection. Shaped Metal Deposition processes like Gas Tungsten Arc Welding (GTAW) allow to locally build-up material in order to provide thickness for a sufficient length of thread engagement. This publication describes the research towards local thickening of a titanium sheet by means of pulsed Tungsten Inert Gas (TIG) droplet deposition, aimed at creating threaded holes for thin shelled bone fracture fixation plates. The influence of current, weld time and amount of filler material on droplet diameter and height is studied.

Abstract. The simulation of machining process is an essential tool in the digitalization of the entire production chain. Currently, these simulations are not sufficiently precise to avoid the use of experimental tests in order to optimize machining operations and guarantee the quality of the machined parts. Some parameters, such as tool-chip contact length, are still underestimated, although they are critical for controlling heat transfer into the tool and implicitly its wear. In order to validate a numerical cutting simulation model, the tool-chip contact length experimentally measured should be used as a comparative quantity, in the same way as the cutting forces and the morphology of the chips is currently used. The objective of this paper is to propose an automation of tool-chip contact length measurements using image processing algorithms. The proposed algorithm was able to identify and measure the tool-chip contact length on more that 75% of images. The algorithm accuracy is evaluated by comparing computed and manually measured tool-chip contact length, for different cutting conditions. It was found that it overestimates the contact length, especially in the case where the image quality is lower.

Abstract. The ZEBRA project aims to advance the circular economy by creating wind turbine blades that can be completely recycled. Currently, Wind turbine blades are fabricated through Vacuum-Assisted Resin Infusion (VARI) using thermoset resins. In this endeavor, the recyclable thermoplastic resin Elium® from Arkema is utilized as a sustainable alternative to traditional thermoset resins. The production of thick and sizable components using reactive resins presents various intertwined physical aspects and difficulties, notably concerning potential overheating during the Elium® radical polymerization process. The optimization of this process necessitates the use of simulation to save the expensive time and effort caused by the experiments. However, to be reliable, these numerical methods must be validated to allow accurate predictions for potential defects with thick and complex parts. The challenge lies in flow front detection in the through-thickness direction. In this work, infusion tests were conducted for thick parts in a testing bench instrumented with a robust monitoring system. QRS sensors are placed through the part thickness to detect the front arrival instantaneously. The simulations are compared and validated to the signals of the QRS sensors for validation. Then the model was used to predict the flow behavior for more complex parts. A 3D flow is observed by the differences in permeability between the flow medium and the fabric, which induces a high difference in resin arrival times to the sensors depending on the position of sensors through the part thickness. The flow simulations showed a good approximation of the experimental results. However, deviations are observed in the flow front position, caused by the disturbance induced by the presence of the sensors.

Abstract. Technical ceramics such as alumina with its temperature stability, high mechanical stiffness, and good dielectric strength at low density, meet the requirements for highly resilient components for promising markets of high-performance electronics and the electrification of mobility. Ceramic components are usually manufactured using powder technology processes since forming of sintered ceramics is not possible due to the lack of plasticity. In this work, we use hydroforming to shape thermoplastic ceramic green tapes prior to sintering to add a third dimension to flat substrates. We developed alumina feedstocks based on a polyamide binder system that were extruded to 1 mm thick tapes, hydroformed, debinded and sintered. Depending on the binder composition, forming temperatures of 45-60 °C were sufficient, whereby precise temperature control was crucial for success. As a result, components with forming depths of up to 5 mm were produced without defects. This process offers the potential to revolutionize this market segment, not only in terms of geometric design freedom and low material waste, but also in terms of profitability of mass production.

Abstract. The evolution of composite component production has been driven by a constant quest for improvements in process efficiency, precision, and repeatability. The eventual transition from traditional hand layup to robotic layup represents a significant step in this evolution. The implementation of robotic layup systems has become increasingly prevalent in the manufacturing industry, particularly in the aerospace and automotive sectors, where lightweight, strength, and precision are mandatory requirements. Ideally, the goal is the development of processes where a highly precise robotic arm could automate the deposition of composite materials onto the mold, providing a certain reduction of human errors, and minimizing material waste and associated costs. In this context, this paper proposes a computational tool that is able to provide automatic layup planning for the robotic layup process. The implemented algorithm incorporates the knowledge of a professional laminator: it can automatically analyze a generic mold surface of complex shape, work out the correct strategies for lamination, and generate instructions for robot movements.

Abstract. Higher efficiency motor becomes an expecting keyword in the sustainable society. The iron core in these motors is fabricated by piercing the amorphous electrical steel sheet with sufficient dimensional accuracy and without defects. However, this material has 2.2 GPa in the tensile strength, no ductility, and over 900 HV in hardness. Furthermore, tool life was limited to be short. In recent years, some new tooling technologies for piercing amorphous electrical steel sheets have been developed to reduce the induced damages into punched sheets．Especially, when using nano-textured tool, the process affected width was more reduced than using the none-textured tools. In the present study, nano-texturing orientation effect on the piercing behavior is investigated and its mechanism is discussed.

Abstract. A 3-D finite element model of abrasion process based on a CEL (Coupled Eulerian-Lagrangian) approach was developed. A scratch test on elastic-perfectly plastic materials with a pyramidal indenter was simulated. The influence of the interfacial friction coefficient f, the geometric parameters of the indenter and the cutting conditions on the overall friction coefficient μ were studied. Subsequently, the finite element simulation results were compared with an analytical model. It was found that the µ increases linearly with the friction coefficient f and the attack angle of grit β. The FE model results present a good agreement with the analytical model results.

Abstract. Multi-material skeletal fixators appear to be a promising approach to reduce failure due to the high stiffness of standard-of-care fixators. Nevertheless, joining different materials is challenging due to their different properties. High-velocity impact welding, a solid-state welding process, involves the collision of a “flyer” (moving) part with a stationary “target” at very high speed (i.e., hundreds of meters per second). In this paper we present a preliminary experimental campaign to use laser impact welding to join NiTi and Mg alloy Mg-1.2Zn-0.5Ca-0.5Mn (wt%) sheets and the parallel development of a finite element model to allow gathering further insights into the complex phenomena involved in the process. Preliminary results show the deposition of the Mg alloy on NiTi sheets by tuning the joining process conditions and promising results of the numerical model in terms of accordance with experiments: these findings provide the basis for further process optimization, numerical model calibration and the application of a valid protocol for multi-material skeletal fixation devices.

Abstract. This study focuses on finding a toolpath strategy for accurately forming geometric details on a preshaped sheet metal part by incremental forming in multiple steps. The final thickness distributions and geometrical accuracy are analyzed for spiraling and dedicated feature toolpath strategies. The results are compared to forming the full part (base shape with details) in a conventional single stage manner. Forming the part in multiple steps did improve the accuracy of the part, by decreasing the underforming of the base shape compared to single stage forming. The observed overforming was highly influenced by the location of the detail. In terms of thickness distributions, the toolpath strategy highly influenced the location of the minimal thickness inside each detail. Here, the dedicated feature toolpath proved to be effective for achieving a more uniform thickness distribution.
