This chapter examines the effects of femoral neck geometry and topological structure on elastic properties. A finite element code is used to calculate the full elastic tensor for thirteen human proximal femur specimens. We show that the micro-structure within the human femoral neck and head gives rise to approximate orthotropic elastic symmetry at the whole bone scale. The finite element code c...

The ability to incorporate detailed geometry into finite element models has allowed researchers to investigate the influence of morphology on performance aspects of skeletal components. This advance has also allowed researchers to explore the effect of different material models, ranging from simple (e.g., isotropic) to complex (e.g., orthotropic), on the response of bone. However, bone's compli...

In laparoscopic operations of abdominal hernias some recurrences still take place, even when applying a surgical mesh. This is usually caused by a failure of the connection between the tissue and the implant. The study deals with the influence of an implant's orientation on forces in joints, which connect the mesh to human tissues. In the paper, the implant is modelled as a membrane structure w...

In vacuum assisted resin transfer molding (VARTM) process, fiber preform defects result very often from inappropriate placement at edge regions when the fiber preform has three-dimensional shape. The unintentional permeability variation is difficult to detect by viewing through the transparent vacuum bag. In this paper, a method was proposed for detecting the local permeability variation of the...

As one possible alternative to the finite element method, interpolation characteristic is a key property that meshless shape functions aspire to. Meanwhile, method can directly impose essential boundary conditions, which undoubtedly an advantage over other methods. In this paper, establishment, implementation, and horizontal comparison of interpolative analyses orthotropic elasticity were studi...
