A new experimental method which allows the direct separation of the components of drying creep due to micro cracking and stress-induced shrinkage is developed, demonstrated and validated. The hasic idea is to compare the curL'CIture creep of heams suhjected to the same hending moment hut rery different axial forces. The results confirm that drying creep has two different sources: microcracking ...

With the rapid development of internet technologies, social networks, and other related areas, user authentication becomes more and more important to protect the data of the users. Password authentication is one of the widely used methods to achieve authentication for legal users and defense against intruders. There have been many password cracking methods developed during the past years, and p...

This paper presents a new control technique for the EDC thermal cracking furnace modeled by sets of ordinary differential equation (ODE) and 2D-partial differential equations (PDEs). The dynamics of coupled 2DPDEs-ODE model have been divided into 2 subsystems, set of state variables of the internal and external cracking coil. With the concept of input-output (I/O) linearization, these inner and...

in this work, ferric coagulation and acid cracking as olive mill wastewater (omw) pretreatments during photocatalysis process were compared in batch recirculation reactor. as ferric ions influence, ferric coagulation has preference over acid cracking. ferric ions influence on intensification of penolic components absorption on tio2 surfacein initial and oxidize organic pollutant during photocat...

The additive manufacturability of nickel-based superalloys for laser powder bed fusion (LPBF) technologies is studied by considering the in-process cracking mechanisms. largely depends on resistance to liquid and solid-state cracking. Herein, we propose a two-parameter-based, heat deformation (HR-DR) model, accounting relation between chemical composition (both major minor elements) susceptibil...

The various mechanisms that have been put forward to explain stress-corrosion cracking are briefly summarized. The experimental observations of stress-corrosion cracking in titanium alloys in widely different environmer a are discussed. Evidence from the literature for and against the possibility that hydrogen plays a role in the stress-corrosion cracking of titanium alloys is documented. An ex...
