Hysteretic Behavior of Random Particulate Composites by the Stochastic Finite Element Method [PDF]

open access: yesMaterials, 2019
Hysteretic behavior of random particulate composite was analyzed using the stochastic finite element method and three independent probabilistic formulations, i.e., generalized iterative stochastic perturbation technique of the tenth order, Monte-Carlo simulation, and semi-analytical method.

Extraction of Fracture Toughness Parameters by Ring-Notched Small Punch Specimen Using Cohesive Model

open access: yesShanghai Jiaotong Daxue xuebao, 2021
The fracture toughness of in-service equipment and irradiation materials can be obtained from the ring-notched small punch specimen. The cohesive model was used to describe the ductile fracture behavior and crack propagation process of T91 steel, and the

Cluster-based Generalized Multiscale Finite Element Method for elliptic PDEs with random coefficients

open access: yes, 2017
We propose a generalized multiscale finite element method (GMsFEM) based on clustering algorithm to study the elliptic PDEs with random coefficients in the multi-query setting. Our method consists of offline and online stages.

Influence of material uncertainties on the RLC parameters of wound inductors modeled using the finite element method

open access: yesOpen Physics, 2018
In this work, we highlight the influence of the material uncertainties (magnetic permeability, electric conductivity of a Mn-Zn ferrite core, and electric permittivity of wire insulation) on the RLC parameters of a wound inductor extracted from the ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
