New plastic joints for plastic orthoses.
Plastic joints for orthoses have more advantages than metal joints. They are lightweight, noiseless comfortable to use, rust proof, corrosion free, and radiolucent. Two types of plastic joints were developed by the authors, one for the ankle joint and the other for the knee joint, elbow joint or hip joint. Polypropylene was chosen as the joint material because of its appropriate flexibility and...
متن کاملCustom moulded plastic spinal orthoses.
A review of fifty patients with wide ranging clinical conditions who had been fitted with one-piece moulded plastic spinal orthoses was carried out to determine prescription criteria for these orthoses. The review showed that patients with scoliosis (idiopathic and paralytic), kyphoscoliosis, as well as a selected number of patients with low back pain derive benefit. Patients with kyphosis and ...
متن کاملNew geometry for TCP: severe plastic deformation of tubes
Since tubes are widely used for different industrial applications, processing of tubes by the Severe Plastic Deformation (SPD) method has been the target of different attempts. Among these attempts, development of SPD processes for tubes based on Equal Channel Angular Pressing (ECAP) has been more successful. As an illustration, Tube Channel Pressing (TCP) has been presented as an attractive SP...
متن کاملAn elastic–plastic interface constitutive model: application to adhesive joints
An interface constitutive model which accounts for both reversible elastic, as well as irreversible inelastic separation-sliding deformations at the interface prior to failure has been developed and implemented in a finite-element computer program. A set of experiments has been conducted to determine the constitutive parameters in the interface model for adhesivelybonded components made from an...
متن کاملElastic-plastic Mode-ii Fracture of Adhesive Joints
A numerical study of the elastic-plastic mode-II fracture of adhesive joints is presented in this paper. A traction-separation law was used to simulate the mode-II interfacial fracture of adhesively-bonded end-notched flexure (E.N.F.) specimens loaded in three-point bending, with extensive plastic deformation accompanying failure. The fracture parameters for the traction-separation law were det...
