Abstract Electron beam powder bed fusion (PBF-EB) of Ni-base superalloys such as CMSX-4 is a demanding process. Using conventional PBF-EB machines, process observation done by mounting optical camera systems on viewing windows at the top build chamber. However, concomitant metallization blocks methods with increasing time. Therefore, quality evaluation normally after utilizing visual inspection...

Abstract The use of post-processing heat treatments is often considered a necessary approach to relax high-magnitude residual stresses (RS) formed during the layerwise additive manufacturing laser powder bed fusion (LPBF). In this work, three treatment strategies using temperatures 450 °C, 800 and 900 °C are applied austenitic stainless steel 316L samples manufactured by LPBF. These encompass s...

In engineering mathematics, the unsaturated nature of soil has a significant impact on seismic bearing capacity solution. However, it generally been neglected in published literature to date. Based kinematic approach limit analysis, present study proposes method for calculating shallow strip footings located soils, taking four common types soils as examples. The modified pseudo-dynamic (MPD) is...

With the proliferation of deep convolutional neural network (CNN) algorithms for mobile processing, limited precision quantization has become an essential tool CNN efficiency. Consequently, various works have sought to design fixed and quantization-focused optimization techniques that minimize induced performance degradation. However, there is little concrete understanding how decisions/best pr...

Quality control of mechanical components is crucial to ensure their expected performance and prevent failure. For manufactured additively, quality performed in-process particularly interesting, as the sequential deposition remelting layers represent a possibility mitigate existing flaws. The first step towards closed-loop that monitoring setup data analytics approach can flag discriminate This ...

The present work aims at building an explicit solution with respect to Functionally Graded Material (FGM) parameter for plate structures. For that, the displacement field is written under a separated variables form: in-plane coordinates x,y, transverse coordinate z and material chosen beforehand. This choice yields non-linear problem that can be solved by iterative process based on classical fi...
