Acoustic Noise Computation of Electrical Motors Using the Boundary Element Method

Energies, 2020
This paper presents a numerical method and computational results for acoustic noise of electromagnetic origin generated by an induction motor. The computation of noise incorporates three levels of numerical calculation steps, combining both the finite ...

Dynamic Damage Quantification of Slab Tracks—Finite Element Models on Winkler Soil and Finite-Element Boundary-Element Models on Continuous Soil

CivilEng, 2022
Train passages over intact or damaged slab tracks on different soils were calculated by two methods. The finite element method (FEM) uses a Winkler soil under the track model by adding a thin “soil layer”.

Three-dimensional eddy current analysis by the boundary element method using vector potential [PDF]

, 1990
A boundary-element method using a magnetic vector potential for eddy-current analysis is described. For three-dimensional (3-D) problems, the tangential and normal components of the vector potential, tangential components of the magnetic flux density ...

An analysis of a two cylinder-fluid interaction at critical gap spacing by a cell boundary element method [PDF]

, 2008
Incompressible viscous, uniform flow past two parallel cylinders of equal diameter at a critical gap spacing g? = 0.90 to 1.10 is investigated using the viscous cell boundary element method. In this critical flow zone an irregular interchange of in-phase

A boundary element approach to buckling of laminated plates subjected to arbitrary in-plane loading [PDF]

, 2002
Laminated plate buckling is analyzed by the boundary element method (BEM). Ignoring bending stretching coupling, a solution is first sought for the membrane stresses due to arbitrary in plane loading.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

The coupled dual boundary element-scaled boundary finite element method for efficient fracture mechanics [PDF]

, 2012
A novel numerical method is presented for applications to general fracture mechanics problems in engineering. The coupled dual boundary element-scaled boundary finite element method (DBE-SBFEM) incorporates the numerical accuracy of the SBFEM and the ...

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

A note on the polynomial approximation of vertex singularities in the boundary element method in three dimensions [PDF]

, 2008
We study polynomial approximations of vertex singularities of the type $r^\lambda |\log r|^\beta$ on three-dimensional surfaces. The analysis focuses on the case when $\lambda > -\frac 12$.
