Experimental and numerical investigation of residual stress stiffening influence on dynamic response of welded structures
MajidiRad, Amir Hossein; Yihun, Yimesker S. (ASME, 2019-11-25)This paper presents the study of welding residual stress-stiffening effect on the dynamic responses and vibrational parameters of welded aluminum parts through an experimental modal analysis and Center Hole Drilling (CHD) ... -
Human factors to develop a safety guard model in human-robot interaction
MajidiRad, Amir Hossein; Maniar, Prasham; Yihun, Yimesker S.; He, Hongsheng (Springer, 2020-04-21)In this research, a strategy to incorporate an assist-as-needed scheme into human-robot collaboration during an object co-lifting and manipulation task is developed. Surface Electromyography (sEMG) signals from the upper-arm ... -
Investigation on welding residual stress effects on modal parameters on AA5056 samples: an experimental and numerical study
MajidiRad, Amir Hossein (Wichita State University, 2017-04-28)Most manufacturing processes introduce some type of residual stress. Unlike some types of residual stress measurement tests that are mostly time-consuming and expensive, modal analysis is a suitable substitute that can ... -
Review of welding residual stress stiffening effect on vibrational characteristics of structures using damage approach and vibratory stress relief implementation
MajidiRad, Amir Hossein; Yihun, Yimesker S. (ASME, 2017)There is a huge amount of research and study on the quality, parameter manipulation, material selection etc. of welding to develop optimized results for specific applications. To have a profound understanding of the process, ... -
Shoulder kinematics assessment towards exoskeleton development
Delgado, Pablo; Alekhya, Sajja; MajidiRad, Amir Hossein; Desai, Jaydip M.; Yihun, Yimesker S. (MDPI AG, 2020-08-11)Neuromuscular and sensorimotor degeneration caused by stroke or any other disease significantly reduce the physical, cognitive, and social well-being across the life span. Mostly, therapeutic interventions are employed in ... -
Upper limb rehabilitation and mobility assistance using robotic devices: a review
MajidiRad, Amir Hossein; Yihun, Yimesker S. (ASME, 2019-11-25)This study is aimed at reviewing the various literature on the robot-based rehabilitation and the associated technical issues, augmentation, utilization, and safeties. During recent years, Biorobotics and Collaborative ...
