This paper presents the development of a new 3D finite element model for simulation UD composites materials under crushing, at mesoscale. It is based on Discrete Ply Model (DPM), enhanced with damage law to represent compression constant stress due localised crushing and its propagation from one another. The aims take into account various types involved in laminates during associated absorbed e...
Introduction: Running poses an essential role in maintaining cardiovascular health. However, it has been demonstrated that 2.5 to 38 injuries per 1,000 hours of running can occur. The purpose of this study was to investigate ground reaction forces components during running with running shoes compared to control shoes in individuals with genu varum. Methods: This study was laboratory and semi-e...
Objective: in normal walking, repetitive vertical ground reaction forces are tansformed on musculo-skeletal system. Magnitude of force during impact is major contributor to overuse injuries. Purpose of this study was the evaluate to effect of standard and beveled heel at orthopedic shoe on vertical ground reaction forces during walking in healthy subjects. Materials & Methods: 30 healthy adu...
Introduction and aim: Taping is a common method used by athletes to improve muscular function. The aim was to assess the immediate effect of femoral external rotational and abductoral taping on three-dimensional ground reaction force characteristics, their time to peak, impulse, displacement of center of pressure, vertical loading rate, and free moment during stance phase of running. Method: 24...
This work presents force control in dual arm planar cooperative space robot for cooperative manipulation by two arms. A docking operation by the two arms of the space manipulator has been carried out. During docking operation, space robot requires mechanical interaction with compliant objects, which encounter force and motion constraints. The gripping force should be such that the object should...
The main objective of this research is to improvethe design and performance of the polyurethane foam-filled thin-walled aluminum grooved circular tubes using multi-response optimization (MRO) technique. The tubes are shaped with the inner and the outer circular grooves at different positions along the axis. For this aim, several numerical simulations using ABAQUS finite element explicit code ar...
