Analysis of the effect of surface mechanical attrition treatment on the mechanical properties of 17-4 PH stainless steel obtained by material extrusion

In this study, the influence of the surface mechanical attrition treatment (SMAT) on a 17-4PH stainless steel made by material extrusion additive manufacturing is investigated under mechanical loading. The evolutions of the deformations at the local…

Fracture mechanisms of an environmental barrier coating under thermomechanical loadings

The introduction of environmental barrier coating (EBC) with SiC/SiC composites in hot components airplanes engines makes it essential to master their behavior in this multiphysical environment. The aim of this paper is to investigate the fracture…

On the benefits of a multiscale domain decomposition method to model-order reduction for frictional contact problems

In this paper, the efficiency of a multiscale strategy based on a domain decomposition method (DDM) for model-order reduction of time-dependent frictional contact problems is presented. The proposed strategy relies on the LArge Time INcrement (LATIN…

Silicon mediated twin formation in laser direct energy deposited 316L stainless steel

Microstructures of two laser direct energy deposited 316L stainless steel samples printed using the same additive manufacturing parameters and primarily differing in their Si content, 2.2wt% (316L-Si) and 0.73wt% (316L), were studied. A larger…

Employing Williams' series for the identification of fracture mechanics parameters from phase-field simulations

Fracture mechanics and damage mechanics are two theories that describe the degradation of the bearing capacity of structures. Fracture mechanics is based on a discontinuous description of cracking, while damage mechanics proposes a continuous…

Deep-learning model for background parenchymal enhancement classification in contrast-enhanced mammography

Background. Breast background parenchymal enhancement (BPE) is correlated with the risk of breast cancer. BPE level is currently assessed by radiologists in contrast-enhanced mammography (CEM) using 4 classes: minimal, mild, moderate and marked, as…
