13. Buckling and Vibration of Functionally Graded Non-uniform Circular Plates Resting on Winkler Foundation
Abstract An investigation on the effect of uniform tensile in-plane force on the radially symmetric vibratory characteristics of functionally graded circular plates of linearly varying thickness along radial direction and resting on a Winkler foundation has been carried out on the basis of classical plate theory. The non-homogeneous mechanical properties of

14. Dynamic analysis and vibration control of a multi-body system using MSC Adams
AbstractIn this paper, modelling and simulation of a multi-body system for its vibration control using sensors and actuators is presented. The model developed on MSC ADAMS consists of six legs connecting moving and base plates using spherical joints with axial rotation of legs constrained. It contains linear actuator collocated with force sensor. Mathematica

15. A new FEM procedure for transverse and longitudinal vibration analysis of thin rectangular plates subjected to a variable velocity moving load along an arbitrary trajectory
A combined plate element is presented for the analysis of transverse and longitudinal vibrations of a thin plate which carries a load moving along an arbitrary trajectory with variable velocity. Depending on the acceleration of the point load on its trajectory on the plate surface, the combined element, which is a combination of the 24 DOF plate element and

16. Ground reaction forces during level ground walking with body weight unloading
Background: Partial body weight support (BWS) systems have been broadly used with treadmills as a strategy for gait training of individuals with gait impairments. Considering that we usually walk on level ground and that BWS is achieved by altering the load on the plantar surface of the foot, it would be important to investigate some ground reaction force (

17. Vertical force calibration of smart force platform using artificial neural networks
INTRODUCTION: The human body may interact with the structures and these interactions are developed through the application of contact forces, for instance due to walking movement. A structure may undergo changes in the dynamic behaviour when subjected to loads and human bodies. The aim of this paper is to propose a methodology using Artificial Neural Network

18. Investigation of the nugget zone corrosion behavior in friction stir welded lap joints of 6061-T6 aluminum alloy
The corrosion behavior at different positions (top and bottom) of the weld nugget zone along the thickness plates in AA6061-T6 aluminum alloys welded by friction stir lap welding, under the conditions of 1000 rpm-60 mm/min and 900 rpm-40 mm/min in a 3.5 wt% NaCl solution, was investigated by Tafel polarization at ambient temperature. The morphology of the nu

19. The impact of tibial torsion measurements on gait analysis kinematics
Objective: To measure and compare tibial torsion values as assessed by goniometry and three-dimensional kinematics. In addition, the impact of each one of these measurements on kinematic and kinetic results for normal gait was determined. Methods: Twenty-three healthy and fully ambulatory patients were assessed, 11 women and 12 men, from 20 to 40 years

23. Comparação entre métodos de fixação interna utilizadas no tratamento de fraturas do ângulo mandibular : estudo mecânico / Comparison of internal fixation methods in the management of mandibular angle fractures : mechanical study
Apesar dos diversos tipos de fixação interna existentes ainda não há um consenso quanto ao método de imobilização das fraturas do ângulo mandibular. Além disso, são poucos os estudos sobre a utilização de placas grade ultimamente lançadas no mercado. O presente estudo visou avaliar comparativamente a resistência entre três tipos de fixação i
