Improved Meshless Local Boundary Integral Equation Method

Chinese Journal of Mechanical Engineering, 2008
Combining the local boundary integral equation with the improved moving least-square method,an improved meshless local boundary integral equation method is presented.In the improved moving least-square method,the weighted orthogonal functions are used as basis ones so that the matrix inverse at each quadrature point is avoided and the algebra equations

Exact solutions for the static bending of Euler-Bernoulli beams using Eringen’s two-phase local/nonlocal model

AIP Advances, 2016
Though widely used in modelling nano- and micro- structures, Eringen’s differential model shows some inconsistencies and recent study has demonstrated its differences between the integral model, which then implies the necessity of using the latter model.

Non-classical heat conduction problem with nonlocal source

Boundary Value Problems, 2017
We consider the non-classical heat conduction equation, in the domain D = R n − 1 × R + $D=\mathbb{R}^{n-1}\times\mathbb{R}^{+}$ , for which the internal energy supply depends on an integral function in the time variable of the heat flux on the boundary ...

Review on localized boundary integral equation: Discrete wavenumber method for 2D irregular layers [PDF]

Earthquake Science, 2010
The pioneer study of simulating the wave field in media with irregular interface belongs to Aki and Larner. Since that many numerical methods on the subject have been developed, such as pure numerical techniques, ray method and boundary method. The boundary method based on boundary integral equation is a semi-analytical method which is suitable to ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A Pure Contour Formulation for the Meshless Local Boundary Integral Equation Method in Thermoelasticity

Computer Modeling in Engineering & Sciences, 2001
A new meshless method for solving stationary thermoelastic boundary value problems is proposed in the present paper. The moving least square (MLS) method is used for the approximation of physical quantities in the local boundary integral equations (LBIE). In stationary thermoelasticity, the temperature and displacement fields are uncoupled.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
