Uncertainty Quantification in Powder Compaction of Metal Alloys
Abstract: In the context of uncertainty in the input data inherent to metal powder compaction process, it is relevant to measure the impact of this variation on the output data. Thus, this paper aims to quantify the uncertainties in the compaction process of metal alloys powders. Monte Carlo simulation is applied to propagate selected uncertainties. In view of the results, there is not a unique value for the porosity of the compacted part, but a range of possible values. Therefore, depending on the dispersion of values, the porosity may not be acceptable to introduce the part into subsequent processes, which may result in lost time due to rework.
