Thermo‐hydro‐mechanical analysis of partially saturated porous materials
Tập 13 Số 7 - Trang 113-143 - 1996
Presents a fully coupled numerical model to simulate the slow transient
phenomena involving heat and mass transfer in deforming partially saturated
porous materials. Makes use of the modified effective stress concept together
with the capillary pressure relationship. Examines phase changes
(evaporation‐condensation(, heat transfer through conduction and convection, as
well as latent heat transfer....
A linear complexity intersection algorithm for discrete element simulation of arbitrary geometries
Tập 12 Số 2 - Trang 185-201 - 1995
We present an algorithm for contact resolution that is valid for a wide variety
of polygonal two dimensional shapes and is of linear computational complexity.
The algorithm is designed for use in discrete element analysis of granular and
multibody systems exhibiting discontinuous behaviour. Contact detection usually
consists of a spatial sorting phase and a contact resolution phase. The spatial
so...
An anisotropic elastoplastic model based on an isotropic formulation
Tập 12 Số 3 - Trang 245-262 - 1995
This paper shows a generalization of the classic isotropic plasticity theory to
be applied to orthotropic or anisotropic materials. This approach assumes the
existence of a real anisotropic space, and other fictitious isotropic space
where a mapped fictitious problem is solved. Both spaces are related by means of
a linear transformation using a fourth order transformation tensor that contains
all ...
THE DISCRETE ELEMENT METHOD FOR ANALYSIS OF FRAGMENTATION OF DISCONTINUA
Tập 9 Số 2 - Trang 145-155 - 1992
This paper is concerned with the determination of the transient stress and
deformational state of plate‐like discontinua subject to flexural cracking. Such
a phenomenon can be easily visualized as the type of fragmentation to floating
sea ice impacted by an ice‐breaker or offshore platform. The discrete element
method is used to solve the dynamic equilibrium equations for each distinct
deformable ...
Numerical simulations for the fluid-thermal-structural interaction lubrication in a tilting pad thrust bearing
Tập 34 Số 4 - Trang 1149-1165 - 2017
Purpose The purpose of this paper is to analyze lubrication characteristics of a
tilting pad thrust bearing considering the effect of the thermal elastic
deformation of the pad and collar. Design/methodology/approach This study used
the fluid–solid interaction (FSI) technique to investigate the lubrication
characteristics of a tilting pad thrust bearing for several typical operating
conditions. Th...
Vibration and fatigue caused by pressure pulsations originating in the vaneless space for a Kaplan turbine with high head
Tập 30 Số 3 - Trang 448-463 - 2013
Implementation and application of elastodynamic boundary element discretizations with improved stability properties
Tập 14 Số 6 - Trang 669-695 - 1997
Direct and indirect time marching boundary element methods often become
numerically unstable. Evidence of, and reasons for, these instabilities is
provided in this paper. Two new time stepping schemes are presented, both of
which are more stable than the existing standard schemes available. In
particular, we introduce the Half‐step scheme, which is more accurate and far
more stable than existing m...
Numerical study on crack propagation in linear elastic multiphase composite materials using phase field method
Tập 36 Số 1 - Trang 307-333 - 2018
PurposeThe purpose of this paper is to develop an efficient numerical method to
study the complex crack initiation and propagation in linear elastic multiphase
composites.Design/methodology/approachA phase field method is developed to study
the complex fracture behavior in multiphase composites. A damage threshold is
introduced for referring crack initiation in the proposed method. The damage
thre...
Numerical algorithms for solving shallow water hydro-sediment-morphodynamic equations
Tập 34 Số 8 - Trang 2836-2861 - 2017
PurposeThe purpose of this paper is to present a fully conservative numerical
algorithm for solving the coupled shallow water hydro-sediment-morphodynamic
equations governing fluvial processes, and also to clarify the performance of a
conventional algorithm, which redistributes the variable water-sediment mixture
density to the source terms of the governing equations and accordingly the
hyperbolic...
NUMERICAL ANALYSIS OF MICROMECHANICAL BEHAVIOUR OF GRANULAR MATERIALS
Tập 9 Số 2 - Trang 211-223 - 1992
A numerical analysis of the micromechanical behaviour of a granular material is
described using a new program MASOM based on Cundall's discrete element method.
In the analysis the individual grains which make up the material are taken to be
deformable 2D polygons of arbitrary size and shape. Contact forces between the
grains are calculated according to Mindlin's solution for frictional contact
bet...
