Numerical homogenization of elliptic PDEs with similar coefficients
, 2018 We consider a sequence of elliptic partial differential equations (PDEs) with different but similar rapidly varying coefficients. Such sequences appear, for example, in splitting schemes for time-dependent problems (with one coefficient per time step ...

Meso-scale modelling of 3D woven composite T-joints with weave variations [PDF]
, 2019 A meso-scale modelling framework is proposed to simulate the 3D woven fibre architectures and the mechanical performance of the composite T-joints, subjected to quasi-static tensile pull-off loading. The proposed method starts with building the realistic

Dynamic Model of Spur Gear Pair with Modulation Internal Excitation
International Journal of Rotating Machinery, 2017 In the actual measurements, vibration and noise spectrum of gear pair often exhibits sidebands around the gear mesh harmonic orders. In this study, a nonlinear time-varying dynamic model of spur gear pair was established to predict the modulation ...

A moving mesh method with variable relaxation time
, 2006 We propose a moving mesh adaptive approach for solving time-dependent partial differential equations. The motion of spatial grid points is governed by a moving mesh PDE (MMPDE) in which a mesh relaxation time \tau is employed as a regularization ...

Non-linear dynamic analysis of geared systems, part 2 [PDF]
A good understanding of the steady state dynamic behavior of a geared system is required in order to design reliable and quiet transmissions. This study focuses on a system containing a spur gear pair with backlash and periodically time-varying mesh ...

Fast iterative solvers for geomechanics in a commercial FE code [PDF]
, 2009 There is a pressing need to improve the feasibility of three-dimensional finite element (FE) methods applied to many problems in civil engineering. This is particularly the case for static analyses in geotechnical engineering: ideally, models would be 3D,
