The goal of this study is to quantify changes in knee joint contact behavior following varying degrees of the medial partial meniscectomy. A previously validated 3D finite element model was used to simulate 11 different meniscectomies. The accompanying changes in the contact pressure on the superior surface of the menisci and tibial plateau were quantified as was the axial strain in the menisci...

The numerical simulation of the crack welding process is reported in this paper. The thermo-electro-structural coupled-field finite element analysis is adopted to investigate the welding process of crack surfaces. In the simulation, the pressure-dependent and temperature-dependent electrical contact conditions are considered. From the results, the crack surfaces can melt and weld together under...

INTRODUCTION The objective of the study is to compare the efficacy of fl at insoles, bone spur pads, pre-fabricated orthotics and customised orthotics in reducing plantar contact pressure of subjects with plantar fasciitis. MATERIALS AND METHODS This is a controlled non-blinded comparative study conducted in a tertiary medical institute. Thirty subjects with unilateral plantar fasciitis betwe...

In engineering design, none of the existing models for calculating contact pressure in pin-loaded lug is fully compatible with actual working conditions. order to obtain a more accurate formula maximum lug, after verifying reliability finite element model PRESCALE measurement film, single-parameter and multi-parameter analysis two types factors affecting distribution compressive surface were co...

BACKGROUND AND OBJECTIVES Injuries of tracheal mucosa in contact with tracheal tube cuff is a function of cuff pressure and exposure time. This study aimed at analyzing injuries of tracheal mucosa in contact with tracheal tube cuff inflated to reach "seal" pressure or limit 25 cmH2O pressure, below critical 30 cmH2O, to prevent tracheal damage. METHODS This study involved 16 dogs submitted to...

V-band clamps are utilised in a wide range of industries to connect together a pair of circular flanges, for ducts, pipes, turbocharger housings and even to form a joint between satellites and their delivery vehicle. In this paper, using a previously developed axisymmetric finite element model, the impact of contact pressure on the contact surface of the V-band clamp was studied and surface rou...

The objective of this study was to examine the effects of patellar resurfacing on patellofemoral joint contact pressure and contact area in total knee arthroplasty. We tested seven fresh-frozen cadaveric knees using a custom knee jig which permits the simulation of physiologic quadriceps loading. Before patellar resurfacing, the mean peak contact pressure of medial and lateral patellofemoral jo...
