Dissimilar joint with good quality and mechanical properties is one of the major problems the industries. One of the most commonly used methods to solve this problem is friction stir welding process. In this paper two different tool pin with simple cylindrical and screwed profile were used to finding optimization of friction stir welding parameters to reach best mixing flow, composite structure...
Objective: Performing repetitive overhead movements puts stress on the shoulder joint, leading to uneven shoulders and pain in the shoulder joint. The purpose of this study was to evaluate and compare the strength and Range of Motion (ROM) of internal and external rotator muscles in volleyball players with and without uneven shoulders. Methods: This is a descriptive and causal-comparative stud...

Present study focuses on the micro-structural and mechanical behavior effect of friction time for similar (AISI 316-AISI 316 and AISI 304-AISI 304) and dissimilar (AISI 304-AISI 316) joint during continuous drive friction welding. The welding carried out with different friction time: 6.5, 8.5 and 10 s while kept all other conditions constant. The effect of that time on the strength, structural ...
Abstract: The effect of phase development on peel strength of alumina-copper metalized joint has been investigated. The alumina-copper joint was prepared in three stages. The alumina substrate was, first, metalized at 1500°C in H2-furnace by a new formulation. In the second step, a nickel layer was electroplated on the metalized layer with approximately 10µm thickness. Finally, copper strip...
In this study, joining of Ni3Al intermetallic compounds using the transient liquid phase (TLP) process with Cu interlayer was investigated. The binding process was carried out in a vacuum furnace at a temperature of 1050 °C for different times of 30, 60, 90 and 120 minutes. The effect of time variation on microstructure and mechanical properties of the joint zone was investigated. The EDS analy...
Manufacturing and Testing techniques were investigated for the development of efficient joining of composite tubes. The stepped lap joining arrangements were studied. Finite element models were developed using ANSYS finite element code for predicting the stress distribution of the joint under the applied loads. Tubes made of graphite/epoxy were considered. The tubes were tested under both tensi...

abstract background: the measurement of hand grip strength has several clinical applications to evaluate chronic hand disability, response to treatment, and work capacity after hand injury. methods: we measured hand grip strength of 41 adults and compared their maximum strength with radiographic indices. results: there was a significant relationship between hand grip strength and carpal height,...
[Purpose] The aim of this study was to determine a relationship between joint angle and muscular strength. In particular, this research investigated the differences in maximum muscular strength and average muscular strength at the knee-joint posture. [Subjects and Methods] The study subjects comprised eight female students in their 20s attending S University in Busan. None of the subjects had f...
