The primary cilium which is an organelle in nearly every cell in the vertebrate body extends out of the cell surface like an antenna and is known as cell sensor of mechanical and chemical stimuli. In previous numerical simulations, researchers modeled this organelle as a cantilevered beam attached to the cell surface. In the present study, however, we present a novel model that accommodates for...

modelling of crack propagation by finite element method under mixed mode conditions is of prime importance in fracture mechanics. this paper describes an application of finite element method to the analysis of mixed mode crack growth in linear elastic fracture mechanics. crack growth process is simulated by an incremental crack-extension analysis based on the maximum principal stress criterion,...

Ab&aet-Finite element procedures fur the dynamic analysis of fluid-structure systems are presented and evaluated. The fluid is assumed to be inviscid and compressible and is described using an updated &ran@an formulation. Variable-number-nodes isopammetric twoand threedimensional elements with hmtped or consistent mass idealization are employed in the finite element discretization, and the incr...

The simulations of underwater implosion, aerodynamics of flexible flapping-wing micro air vehicles, aeroelastic tailoring of racing cars, and high-G maneuvers of fighter aircraft share the challenge of computing fluid-structure interactions in highly nonlinear multi-material domains. Indeed, the implosive collapse of a submerged, gas-filled structure and its subsequent effect on the structural ...

A new method is developed to simulate the fully coupled motion involving an ellipsoidal particle and the ambient fluid. This method essentially reduces a two-phase flow problem into a single-phase fluid flow problem. The momentum exchange at the interface between the particle and the fluid is computed in a spectral element method. To validate this method and demonstrate the accuracy of the resu...
