Abstract Hybrid bonded-rived joint combines bonding and riveting has become one of the most important connection forms in composite materials. This paper investigates analyzes influence geometric parameters CFRP hybrid joints on load-bearing strength. The finite element method is used to analyze strength bonded/riveted between carbon fiber metal under tensile load. different ratios joint’s e/D,...

BACKGROUND Knee osteoarthritis (OA) is a mechanically driven disease, and it is suggested that medial tibiofemoral knee-joint load increases with pharmacologic pain relief, indicating that pharmacologic pain relief may be positively associated with disease progression. Treatment modalities that can both relieve pain and reduce knee-joint load would be preferable. The knee-joint load is influenc...

1. Abstract A 2-dimensional lumbar spine is modeled with 64 back muscles and the static behavior of the model is predicted using an optimization technique. The goal of this study was to investigate if a follower load can be produced by the back muscles for enhancing the mechanical stability of the lumbar spine in a quiet standing posture. Recent studies demonstrated that the stability of the lu...

in this study, a new servo control system is presented for the overhead crane based on discrete-time state feedback approach. it provides both robust tracking and load swing suppression. inspired from independent joint and computed torque control in robot manipulator field, a new model is derived in which the crane actuators are considered as the main plant. the crane nonlinearities are then tr...

The purpose of this study was to determine the effect of load on lower extremity biomechanics during the pull phase of the clean. Kinematic and kinetic data of the 3 joints of the lower extremity were collected while participants performed multiple sets of cleans at 3 percentages: 65, 75, and 85% of 1 repetition maximum (1RM). General linear models with repeated measures were used to assess the...

For many years U.S. design codes modeled the design values of a multiple-bolt joint as the design value of a single-bolt connection multiplied by the number of bolts. The provisions were based on research conducted by Trayer (1932) who observed an equal distribution of load among bolts. This was despite the fact that research conducted as early as in the late 19 century suggested an uneven load...

The movement patterns one sees when loads placed on a joint are incrementally increased provides valuable insight as to how a joint functions during different everyday activities. This author describes a simple, yet effective method of assessing the thumb carpometacarpal joint as load demands increase. It may be used as an evaluative tool or as an adjunct to treatment.

A computational model of the tibiofemoral joint utilizing the discrete element analysis method has been developed and validated with human cadaveric knees. The computational method can predict load distributions to within a root mean square error (RMSE) of 3.6%. The model incorporates subject-specific joint geometry and the health of the subjects' articular cartilage to determine the cartilage ...

The purpose of this study was to determine the effects of age, load amount and load symmetry on lower extremity kinematics during carrying tasks. Forty-two participants in four age groups (8-10 years, 12-14 years, 15-17 years and adults) carried loads of 0%, 10% and 20% body weight (BW) in large or small buckets unilaterally and bilaterally. Reflective markers were tracked to determine total jo...
