MODERN FINITE VOLUME METHODS SOLVING INTERNAL FLOW PROBLEMS
TASK Quarterly, 2002 The paper deals with explicit and implicit finite difference and mainly finite volume schemes that have been commonly used in last years for compressible and incompressible fluid flow problems.

On the high order FV schemes for compressible flows [PDF]
Applied and Computational Mechanics, 2007 This work describes a high order finite volume scheme for compressible flows. The differences between the basic low order scheme and the second and third order schemes are documented for the case of inviscid flows in a channel as well as for the case of ...

From Statistical Correlations to Stochasticity and Size Effects in Sub-Micron Crystal Plasticity
Metals, 2019 Metals in small volumes display a strong dependence on initial conditions, which translates into size effects and stochastic mechanical responses. In the context of crystal plasticity, this amounts to the role of pre-existing dislocation configurations ...

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System
Advanced Engineering Materials, EarlyView.Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators
Advanced Engineering Materials, EarlyView.Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

A free boundary model for transport-induced neurite growth
European Journal of Applied MathematicsWe introduce a free boundary model to study the effect of vesicle transport onto neurite growth. It consists of systems of drift-diffusion equations describing the evolution of the density of antero- and retrograde vesicles in each neurite coupled to ...

BMC Musculoskeletal Disorders, 2020 Background Polymethylmethacrylate (PMMA) is commonly used for cement-augmented pedicle screw instrumentation (CAPSI) to improve the fixation stability and reduce the risk of screw loosening in the osteoporotic thoracolumbar spine.

Advanced Engineering Materials, EarlyView.A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

THE EIGENSPECTRUM OF A FINITE VOLUME MATRIX
, 2022 The discretisation of partial differential equations using the Finite Volume Method results in linear systems with square, sparse coefficient matrices, which have symmetric addressing. The dimension of the coefficient matrix is equal to the number of finite volumes in the spatial discretisation, i.e. computational mesh.
