Torsional fretting behavior of TC4 titanium alloy has been investigated at different parameters to explore the wear resistance and mechanisms alloy. The loops, dissipated friction energy torque under normal load (100N 200N), angular displacement (±0.5° ±2°) frequency (10Hz 15Hz) were studied reveal mechanical during fretting. Results showed that made difference in while was most important facto...

This work presents the effects of strain rate on the tensile properties and fracture morphologies of AHSS-DP 350/600 subjected to LSP. Fatigue crack growth test was performed to evaluate fatigue behavior in the metallic plate of AHSS-DP350/600. However, this material is used in automobile industry and enhancing it fatigue resistance is a challenge in material engineering. In order to evaluate a...

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 ...

AIM To evaluate the efficacy and safety of phacoemulsification using torsional modality with different parameter settings for hard nucleus cataract extraction. DESIGN A prospective, randomised clinical study. METHODS A clinical practice study conducted at the Cataract Service, Zhongshan Ophthalmic Center, Sun-Yat-Sen University, and Guangzhou. One eye each from 198 consecutive patients with...

The geometric optimization of orthopedic screws can considerably increase their orthopedic efficiency. Due to the high geometric parameters of orthopedic screws, a finite element simulation is an effective tool for analyzing and forecasting the effect of the parameters on the load-bearing capacity of different types of screws and bones. Thus, in the present study, the tensile strength of a typi...
