By combining experimental SPR tests with a finite element (FE) model, the influences of top sheet thickness (Tt), bottom (Tb) and rivet length (L) on joint formation mechanisms were systematically investigated in this study. Single factor experiments firstly conducted to uncover three joining parameters' effects results. Interrupted also performed confirm prediction accuracy FE model process. T...

Defective DNA repair by homologous recombination (HR) is thought to be a major contributor to tumorigenesis in individuals carrying Brca1 mutations. Here, we show that DNA breaks in Brca1-deficient cells are aberrantly joined into complex chromosome rearrangements by a process dependent on the nonhomologous end-joining (NHEJ) factors 53BP1 and DNA ligase 4. Loss of 53BP1 alleviates hypersensiti...

Various welding methods are used to produce non-detachable joints of plastic parts. These friction (FW), friction-stir (FSW), ultrasonic welding, chemical bonding, and hot plate welding. Rotary (RFW) method, which is one the FW methods, generally in joining filter parts water treatment devices. After RFW processes, semi-melted accumulations tend occur on interior surfaces In some cases, particl...

7075 T6 aluminum alloys are applied in aircraft construction. The success of their weldability is a technological challenge bringing advantages the lightening structures. This work was carried out aim to analyze mechanical behavior and microstructural evolution sheets welded by TIG process, applying pulsed current. A notable change occurred our materials thermal effect, resulting degradation pr...

It is important to join materials for systems that require high-performance and minimize the defects may occur during this joining. Welding most common way joining but lightweight similar/ dissimilar materials, Friction Stir preferable its properties. Lightweight durable such as aluminum alloys are widely used in sectors defense industry, aerospace automotive high-speed train manufacturing. Som...

T his study aims to demonstrate that joining in risk sharing network leads to the reduction in incomes volatility. In this respect, income variance for a group of members in an informal insurance is modelled in which income variance prior to joining risk sharing network and after joining is analyzed statistically. A Monte Carlo simulation technique is used to prove the result. To extend an...

The widespread application of thermoplastic polymers in different aspects of industries has motivated researchers and companies to improve and upgrade their forming, joining and assembling processes to overcome their limitations. One of the newest joining methods of thermoplastics is friction stir welding which is based on frictional heat generated through contact between a rotating tool and th...
