simultaneous dislocation of both interphalangeal (ip) joints of same finger is a highly uncommon finding. and dislocation of metacarpophalangeal (mcp) joint along with interphalangeal joints of thumb are reported in literatures if, scarcely. here we are reporting the three cases, comprising of double dislocation of ip joints in little finger in two patients and simultaneous mcp and ip joint dis...

This work deals with a methodology to assess the influence of the spherical clearance joints in spatial multibody systems. The methodology is based on the Cartesian coordinates, with the dynamics of the joint elements modeled as impacting bodies and controlled by contact forces. The impacts and contacts are described by a continuous contact force model that accounts for geometric and mechanical...

This paper suggests a simple yet efficient experimental method to record the displacement of the shaft in a revolute joint with clearance. Two light and compliant cantilevers have been mounted on the rocker, each being instrumented with two strain gauges which can measure bending. These cantilevers are mounted in an orthogonal fashion, near the axis of the revolute joint, each touching the shaf...

This paper reviews Fibre Reinforced Polymer (FRP) composites in Civil Engineering applications. Three FRP types are used Structural Engineering: profiles for new construction, rebars and strengthening systems. Basic materials (fibres resins), manufacturing processes material properties discussed. The focus of the is on all-FRP new-build structures their joints. All-FRP use pultruded profiles. T...

arthrogryposis as a congenital malformation that refers to the fixed flexion of one or more joints as a result of stiffness or limited movements of multiple joints, change of posture and limb function due to permanent contracture of joints and wasting of muscles that usually occur at early stage of gestation. this report describes congenital arthrogryposis associated with musculoskeletal defect...

The flight control effects and quality of the aircraft are influenced by flap actuation system directly. main motivation this research is to develop a rigid-flexible model with clearance explore coupling joints flexible bodies on system’s dynamic characteristics. A modified contact force used joint small clearance, heavy load, large area. Then, effectiveness an embedded modeling method verified...
