Summary

The isogeometric boundary element method refers to the numerical simulation technique that employs the basis functions used for building Computer-Aided Design (CAD) models to discretize Boundary Integral Equations in Computer-Aided Engineering (CAE). The isogeometric boundary element method is based on boundary-representation like CAD, and thus it can immediately utilize the surface data of CAD models without volume parameterization. As such, the isogeometric boundary element method achieves closer integration of CAD and CAE compared to the isogeometric analysis in the context of the finite element method. Additionally, the isogeometric boundary element method inherits the advantages of conventional boundary element methods in infinite domain, moving boundary problems, etc. Since its inception, the isogeometric boundary element method has drawn extensive attention and exhibits its potential in computational mechanics. However, many issues remain unresolved in both method development and engineering applications. Therefore, we initiate this special issue on the recent developments, challenges and opportunities of the isogeometric boundary element method and its potential applications in different areas.

 

Topics of interest include but are not restricted to:

1. Novel CAD modeling techniques in isogeometric boundary element methods.

  • Monte Carlo Simulation of Fractures Using Isogeometric Boundary Element Methods Based on POD-RBF
  • Abstract This paper presents a novel framework for stochastic analysis of linear elastic fracture problems. Monte Carlo simulation (MCs) is adopted to address the multi-dimensional uncertainties, whose computation cost is reduced by combination of Proper Orthogonal Decomposition (POD) and the Radial Basis Function (RBF). In order to avoid re-meshing and retain the geometric exactness, isogeometric boundary element method (IGABEM) is employed for simulation, in which the Non-Uniform Rational B-splines (NURBS) are employed for representing the crack surfaces and discretizing dual boundary integral equations. The stress intensity factors (SIFs) are extracted by M integral method. The numerical examples simulate several cracked structures… More
