There has been increasing demand to research the measuring method to characterize the batch consistency of contact rivets. An automated test equipment has been described that makes it possible to measure the electrical contact resistance with high efficiency. The relationship between contact force and contact resistance during the loading and unloading process was measured explicitly using AgPd...

E14 WOUNDS www.woundsresearch.com Abstract: xxxxx Abstract: Traumatic spleen rupture is a common abdominal emergency that requires immediate diagnosis and prompt surgical treatment to ensure the patient’s survival. The operative indications of spleenpreserving therapy and the choice of surgical methods directly affect prognosis. Preservation of splenic function is the principle clinical aim, an...

This work investigates the influence of Friction Riveting processing conditions on FR4-PCB substrate/AA2024 rivet joints in terms process temperature evolution, joint formation, and physical-chemical mechanical properties. The were manufactured using 4 mm diameter AA-2024-T3 rivets FR4 laminates 1.5 thickness with single or double copper-clad layers. evolution was recorded substrate surface cor...

Strength reduction in structures like an aircraft could be resulted as cyclic loads over a period of time and is an important factor for structural life prediction. Service loads are emphasized at the regions of stress concentration, mostly at the connection of components. The initial flaw prompting the service life was expected by using the Equivalent Initial Flaw Size (EIFS) which has been re...

Self-pierce riveting (SPR) is a major joining method used in the automotive industry. However, there still lacks fast and easy-to-use joint quality prediction tool available for engineers. In this study, simple but effective regression analysis was applied to quickly predict SPR quality. Two models were developed of interlock minimum remaining bottom sheet thickness (Tmin). The accuracy validat...
