Finite-element analysis cylindrical-material model

Guo et al. 5 ook resin matrix composites filled with SIC whiskers as an example and analyzed the effect of the inter-facial zone state on mechanical properties of composite materials by finite element method. They hold that when whiskers are randomly distributed in a resin matrix with a certain volume fraction, they demonstrate a periodic distribution from the statistical point of view. It is assumed that the SIC whisker-reinforced phase in resin matrix composites is arranged in one direction without considering the effect of whisker orientation, the analysis model can be simplified as a rotator shape with the large cylindrical part as the polymer matrix and the small cylindrical part as the whisker. Therefore, a three-dimensional problem turns into an axisymmetric problem, and only a quarter part of the body model is taken in the calculation. [Pg.191]

Theret et al. [1988] analyzed the micropipette experiment with endothelial cell. The cell was interpreted as a linear elastic isotropic half-space, and the pipette was considered as an axisymmetric rigid ptmch. This approach was later extended to a viscoelastic material of the cell and to the model of the cell as a deformable layer. The solutions were obtained both analytically by using the Laplace transform and numerically by using the finite element method. Spector et al. [ 1998] analyzed the application of the micropipette to a cylindrical cochlear outer hair cell. The cell composite membrane (wall) was treated as an orthotropic elastic shell, and the corresponding problem was solved in terms of Fourier series. Recently, Hochmuth [2000] reviewed the micropipette technique applied to the analysis of the cellular properties. [Pg.1049]

A finite element model of the rivet and pin system was developed to analyze rivet deployment and optimize the design of the system. The model includes the rivet body and pin and a cylindrical portion of bone. A finite sliding contact analysis with friction (Abaqus Version 5.8) was conducted in two steps placement of the rivet body into a hole in bone and insertion of the pin into the rivet body. The material properties were as follows Bone E=2 GPa, Poisson s ratio=0.3 and polymer E=2.5 GPA, Poisson s ratio=0.45. The friction coefficient on all surfaces was 0.1. [Pg.350]
