In an effort to reduce the incidence of decubitus ulcers among wheelchair users, current work in cushion design concentrates on minimizing the pressure at the buttock-cushion interface. Finite element analysis can show the stress levels throughout the soft tissue between the cushion and the ischial tuberosity and give designers a better indication of the effects of a particular cushion. Finite ...

statement of problem: t-loop is one of the most popular closing loops in orthodontic profession. however its activation is in the contrary to bouschinger effect theory, since the formed bends would be opened during activation. the purpose of this study was to add a helix in a way to be more respondent to the bouschinger effect theory. objectives: to compare the load deflection, maximal elastic ...

The dimensional, geometrical, thermal and tool deflection errors which have a big portion of the overall error machined parts need more attention in precision components produced by using CNC machine tools. As result, it is essential to simulate compensate order increase accuracy parts. In analyse real manufactured virtual environments, machining systems are proposed. this paper, application sy...

in this paper deflection and free vibration of sandwich panel is studied. the core of sandwich panels is made of hexagonal honeycomb and faces are made of two different materials of carbon fiber reinforced plastic and k-aryl/epoxy covering. the governing equations are deduced from the first order sheer deformation theory (fsdt) and they are solved using generalized differential quadrature metho...

A simulation method for the wear of a dynamic seal in an axial flux hub motor is proposed this work. quasi-3D magnetic model without deflection between axes stator and rotor built. An analytical unbalanced force considering cogging effect presented based on model. Boundary conditions are obtained through solving FE motor. Both structural thermal built thermal–structural coupling given. displaye...

Cells in the rodent barrel cortex respond to vibrissa deflection with a brief excitatory component and a longer suppressive component. The response to a given deflection is thus scaled because of suppression induced by a preceding deflection, causing the neuronal response to be linked to the temporal properties of the peripheral stimulus. A paired-deflection stimulus was used to characterize th...
