The dynamic response of complex equipment under mixed-mode loading is significant for structural design. Bolted joints are the primary connection mode subsystem assembly, and degradation bolted may reduce safety reliability equipment. Iwan model widely used to describe joints, which has been continuously revised experimentally verified. classic a static that lacks predictive ability. latest can...

The contact area and pressure distribution in a wheel/rail contact is essential information required in any fatigue or wear calculations to determine design life, re-grinding, and maintenance schedules. As wheel or rail wear or surface damage takes place the contact patch size and shape will change. This leads to a redistribution of the contact stresses. The aim of this work was to use ultrasou...

Cartilage is responsive to the loading imposed during cyclic routine activities. However, the local relation between cartilage in terms of thickness distribution and biochemical composition and the local contact pressure during walking has not been established. The objective of this study was to evaluate the relation between cartilage thickness, proteoglycan and collagen concentration in the kn...

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...
