The current article presents an open-source toolbox for mechanics and fluid-solid interaction simulations based on library OpenFOAM. object-oriented design is outlined, where emphasis been given code use, comprehension, maintenance extension. capabilities are demonstrated number representative test problems, comparisons with solutions.

SUMMARY Correct calculation of stresses at the interface bonded or otherwise joined materials plays a significant role in many applications. It is therefore important that traction material calculated as accurately possible. This paper describes procedures can be employed to achieve this goal by using centre‐based finite‐volume method. Total decomposing it into normal and tangential components, both being each side interface, applying continuity assumption. The way which approximation...

This paper explores the potential methods for evaluating a healing system asphalt pavements. The under investigation involves compartmented calcium-alginate fibres encapsulating an binder agent (rejuvenator). presents novel method of incorporating rejuvenators into pavement mixtures. are used to distribute rejuvenator throughout mixture, thereby overcoming some problems associated with alternate methods, i.e., spherical capsules and hollow fibres. efficiency be evaluated in this include: (i)...

This paper establishes a procedure for numerical analysis of hip joint using the finite volume method. Patient-specific geometry is segmented directly from computed tomography and magnetic resonance imaging datasets resulting bone surfaces are processed into form suitable meshing. A high resolution continuum tetrahedral mesh has been generated, where sandwich model approach adopted; bones represented as stiffer cortical shells surrounding more flexible cancellous cores. Cartilage included...

This paper explores the potential use of conductive alginate capsules encapsulating a bitumen rejuvenator as new extrinsic self-healing asphalt method. The combine two existing technologies: (1) encapsulation and (2) induction heating to create system that will provide rapid effective pavement repair. work presents proof concept for process, which involves embedding into mortar mixture survival rate in mixture. A drip capsule production process was adopted scaled up 20l wet at 0.22 l/min. To...

Abstract A percolation model with nucleation and object growth is studied by Monte Carlo simulations on a triangular lattice finite-size impurities. The growing objects are needle-like self-avoiding random walk chains. Results obtained for three different shapes of impurities covering sites—needle-like, angled triangular. In each run through the system, initially randomly occupied specified shape at given concentration <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Blood flow through arteries represents a very complex, fluid-structure interaction (FSI) problem. Strong coupling between the blood and artery is due to relatively low stiffness of compared that blood. Hence, pressure exerted by flowing on wall can result in considerable deformations artery, vice-versa, arterial turn affect flow. In present work, finite volume method employed solve problem where compressible fluid, representing blood, flows healthy as well unhealthy, i.e., partly stiffened...

Frequently, attachments are approximated as point forces; however, accurate local mechanics requires more realistic forces. This paper describes development mapped Hill‐type muscle models boundary conditions for finite volume hip joint, where calculated fibres map continuously between attachment sites. The...

Percolation properties of two-component mixtures are studied by Monte Carlo simulations. Objects deposited onto a substrate according to the random sequential adsorption model. Various shapes making made self-avoiding walks on triangular lattice. threshold for objects covering same number sites is always lower than more compact object, and it can be even both components. Mixtures percolating non-percolating almost percolate, but percolation higher component. Adding shape high connectivity...
