The presented paper describes a method for micro precision assembly of very small objects like future microchips, which have a lateral expansion equal to or smaller than 500 μm. The modelling and simulation of a fluidicbased micro assembly method for a microchip with a dimension of (500 x 500 x 100) μm3 is performed with COMSOL Multiphysics. The finite element method is used for modelling and s...

The structural-acoustic optimization shows high potential in minimization of radiated noise especially for thin shell geometries. Acoustic design sensitivity analysis can provide information on how the geometry change affects the acoustic performance of the given structure, so it is an important step of the acoustic design and optimization processes. But the sensitivity analysis of the structur...

We propose and analyze a novel, second-order in time, partitioned method for the interaction between an incompressible, viscous fluid and a thin, elastic structure. The proposed numerical method is based on the Crank–Nicolson discretization scheme, which is used to decouple the system into a fluid subproblem and a structure subproblem. The scheme is loosely coupled, and therefore at every time ...

This paper presents a new approach to study the effects of temperature on the poroelastic and viscoelastic behavior of articular cartilage. Biphasic solid-fluid mixture theory is applied to study the poro-mechancial behavior of articular cartilage in a fully saturated state. The balance of linear momentum, mass, and energy are considered to describe deformation of the solid skeleton, pore fluid...

• Two types of multiscale and monolithic ALE-FEM are developed for the hemodynamic FSI problem that involves aneurysm progression. The heterogeneous method (HMM) seamless (SMM) integrated into ALE-FEM. can predict long-term risk within a short time cardiovascular biological simulations. is numerically validated by 2D example in terms its approximation accuracy. HMM/ALE-FEM applied to AAA patien...

This paper presents a study of the dual reciprocity boundary element method (DRBEM) for the laminar heat convection problem between two coaxial cylinders with constant heat flux boundary condition. DRBEM is one of the most successful technique used to transform the domain integrals arising from the nonhomogeneous term of the Poisson equation into equivalent boundary only integrals. This recentl...
