In this study, the elastic stiffness and the degree of anisotropy will be compared for the femur human and bovine bones are presented. A scale for measuring the overall elastic stiffness of the bone at different locations is introduced and its correlation with the calculated bulk modulus is analyzed. Based on constructing orthonormal tensor basis elements using the form-invariant expressions, t...

The objective of this study is to evaluate the use of 1-D and 2-D compact heat transfer models for thermal design, optimization, and performance evaluation in electronic packaging. A model for heat spreading in orthotropic materials is developed. A resistance network analysis for calculation of heat transfer rate and junction temperatures has been carried out. A refrigeration cooled server pack...

Understanding the mechanical and physical behaviour of layered orthotropic material is an essential key step in performance assessment of composite structures and sandwich structures. At the University of Southampton, UK, work has been conducted in analytical, numerical and experimental techniques for damage assessment of composite materials and structures. Data-rich experimental mechanics tech...

This paper presents a simplified simulation technique for orthotropic viscoelastic films. Wrinkling is detected by a combined stress-strain criterion and an iterative scheme searches for the wrinkle angle using a pseudo-elastic material stiffness matrix based on a nonlinear viscoelastic constitutive model. This simplified model has been implemented in ABAQUS/Explicit and is able to compute the ...

In this investigation, a modified Fourier solution based on the Mindlin plate theory is developed for the free vibration problems of orthotropic rectangular Mindlin plates subjected to general boundary supports. In this solution approach, regardless of the boundary conditions, the plate transverse deflection and rotation due to bending are invariantly expressed as a new form of trigonometric se...

The present work addresses the problem of determining under what conditions the impending slip state or the steady sliding of a linear elastic orthotropic layer or half space with respect to a rigid flat obstacle is dynamically unstable. In other words, we search the conditions for the occurrence of smooth exponentially growing dynamic solutions with perturbed initial conditions arbitrarily clo...

PURPOSE To identify strabismus-related proteins, we performed proteome analysis in monozygotic twins with discordance of congenital esotropic phenotypes and in normal children. METHODS Surface-enhanced laser desorption/ ionization time-of-flight mass spectrometry (SELDI-TOF-MS) technology was used to detect changes in protein expression in a pair of twins with discordant esotropic phenotypes ...
