Numerical simulations are an essential tool for material selection and predicting the viability and lifetime of refractories that are usually utilized in high temperature environments. However, the satisfactory modeling of such materials requires parameters that describe the thermomechanical behavior for in-service conditions. This project aims to develop tools to allow for the acquisitio…
A first part is related to the end of the master's project of Rafael Vargas (Wedge Splitting Test - WST - at room temperature, #2017/05678-6), and its defense. A second part will deal with the definition of the PhD work of Rafael Vargas for which a joint Brazilian/French supervision (cotutelle) is aimed for. One key aspect of that work is related to high temperature WSTs on refractories w…
Numerical simulation is an important tool to reduce production costs and improve the control of properties and dimensions of parts produced by pressing and sintering of powders. However, the numerical simulation of such process is complex because the constitutive models demand a great number of parameters. The proposal of this project is the identification of constitutive models for compu…
Numerical simulation is a powerful tool to reduce production costs in the pressing and sintering process. As an example, it may improve dimensional control and the final mechanical properties of the produced parts. On these aspects, a satisfactory prediction of mechanical properties in green compacts is essential to ensure the integrity of the piece in a future process such as green machi…
Refractory castables are crucial materials for transformation industries due to their capacity to ensure functional properties of interest at high temperatures or corrosive environments. Although these materials are resistant, crack initiation is inevitable in such extreme conditions. Therefore, further understanding about crack propagation resistance is mandatory since these defects can …
The proposal of this research project is to develop an experimental procedure for the validation of numerical models during polytetrafluoroethylene (PTFE) pressing. These Finite-Element models are applied during the simulation of the compaction stage of PTFE, which strongly influences the mechanical properties of the final compacted part. Besides, this simulation has extreme importance fo…

High temperature and corrosive environments in which castable refractories are utilized involve high risks. In this context, the characterization of their fracture properties becomes extremely important, and an essential tool for the correct selection, application, development and research of these materials. However, crack propagation features depend on the underlying microstructure and …
PTFE (polytetrafluoroethylene) is a polymer with distinguished properties, commonly used in applications when high working temperatures (up to 260°C) and chemical stability are needed. This material exhibits high viscosity even above the melting temperature Tm(H327°C, for first melting), thus, to form PTFE parts, polymer granules are cold-pressed and sintered. The costs of this manufactur…
