This study proposes damage detection algorithms for multistory shear structures that only need the first two or three natural frequencies. The methods are able to determine the location and severity of damage on the basis of damage location indices (DLI) and damage quantification indices (DQI) consisting of the changes in the first few squared natural frequencies of the undamaged and damaged st...

Background Simple elbow dislocations are a commonly seen joint dislocation involving a sequential disruption of the soft tissue stabilisers without a significant associated fracture. Methods A selective literature search was performed and personal surgical experiences are reported. Results The majority of these injuries can be treated with expedient closed reduction, with the intact bony co...

This paper investigates the effects of tool holder materials on chatter vibration in turning operations. The study uses a complex dynamic model with two degrees freedom for orthogonal cutting system. Tool holders made from different materials, including Al 5083, 6082, 7012, and standard 4140 material, were subjected to investigate their process damping capabilities. found that allows higher sta...
