A method to simulate orthotropic behaviour in thin shell finite elements is proposed. The approach is based on the transformation of shape function derivatives, resulting in a new orthogonal basis aligned to a specified preferred direction for all elements. This transformation is carried out solely in the undeformed state leaving minimal additional impact on the computational effort expended to...

This paper is the second part of free vibration and stability analysis thick isotropic orthotropic plates. The support condition CCCC CCFC was considered by applying alternative II theory based on polynomial shape function. work application formulation earlier derived using Ritz method. frequency values first mode critical loads obtained were compared with those order shear deformation theory. ...

The hydroelastic interaction between an underwater explosion and an elastic plate is investigated num- erically through a domain-decomposition strategy. The three-dimensional features of the problem require a large computational effort, which is reduced through a weak coupling between a one-dimensional radial blast solver, which resolves the blast evolution far from the boundaries, and a three-...

6 Patient-specific high order finite-element (FE) models of human femurs based on quantitative computer tomography (QCT) with inhomogeneous orthotropic and isotropic material properties are addressed. The point-wise orthotropic properties are determined by a micromechanics (MM) based approach in conjunction with experimental observations at the osteon level, and two methods for determining the ...

Abstract We present a semi-analytical method for computing the reflection and transmission coefficients at joints connecting an arbitrary number of semi-infinite orthotropic plates based on line-junction approximation. use wave approach describe reflection, mode conversion between eigenmodes vibro-acoustic equations plates. A detailed derivation is presented here first time meeting junction wit...

Artificial foam structures are used in all kinds of applications, for example, filters, where non‐metallic inclusions filtered out the molten metal. The flow‐through fluid leads to a mechanical loading, which is influenced by flow velocity, viscosity fluid, morphology, and shape filter. Analytical numerical approaches being study influence different parameters on response impact local stresses ...

In this study, we sought to assess the cardiopulmonary functions in three pediatric heart transplant recipients, two of whom are with dilated cardiomyopathy, whereas one is with cyanotic heart disease, in early postoperative period. Cardiopulmonary exercise testing was performed using an incremental cycling at 1 mo after surgery. The results revealed that our study subjects had obvious impairme...

Mandibular condyle plays an important role in the growth and reconstruction of the temporomandibular joint (TMJ). We aimed to obtain orthotropic elastic parameters of the condyle using a continuous-wave ultrasonic technique and to observe the effects of condylar elastic parameters on stress distribution of the TMJ using finite element analysis (FEA). Using the ultrasonic technique, all nine ela...
