All materials have been historically tested at static loading conditions. With the advent of technology, the study of behaviour of materials at high strain rate was done using various methods. The principle of split Hopkinson bar was used to study high strain rate of material in the range of 102s-1 to 103s-1. Split Hopkinson bars were designed for all three modes of deformation and extensively ...

We have previously investigated the formation of water-CO2 interface by means of a drop tensiometer [1]. In presence of CO2 , the interaction between the two adjacent phases leads to an organization of interfacial cluster network which controls the tension and the mechanical properties of the interface. The formation of those clusters at CO2 pressure lower than 80 bar inhibits the adsorption of...

The basic form of the quark condensate for arbitrary values external magnetic field and temperature, is derived using equations with account confinement. resulting expression chiral shown to be proportional square singlet $q\bar q$ ground state wave function at origin, $|\phi_0(0)|^2$. For light quarks without condensates are $\sigma^{3/2}$ ($\sigma$ string tension). Numerical results presented...

A brief review of the technological advances of the Hopkinson bar technique in tension for the study of irradiated/non-irradiated nuclear materials and the development of this technology for large specimens is presented. Comparisons are made of the dynamic behaviour of non-irradiated and irradiated materials previously subjected to creep, low cycle fatigue and irradiation (2, 10 and 30 displace...

We show, from a diabatic analysis of Lattice results for string breaking, that mixing $Q\bar{Q}$ with open-flavor meson-meson configurations may be expressed through potential which is order $1 / m_{Q}$. A relation between the minimum breaking energy gap and tension comes out naturally. Using this relation, matching $b\bar{b}$ QCD data, we study in $c\bar{c}$ case without any additional paramet...

Low-iron ultra-clear float glass (LIFG) has been widely used in landmark and large-scale buildings recent years due to its aesthetic characteristics. A better understanding of the dynamic mechanical properties LIFG is essential for blast resistance analysis design facades. This paper presents a series quasi-static tests (using Split-Hopkinson-Pressure-Bar) study compressive tensile behavior LIF...

Membrane nanopores are central players for a range of important cellular membrane remodeling processes as well as membrane rupture. Understanding pore formation in tense membranes requires comprehension of the molecular mechanism of pore formation and the associated free energy change as a function of the membrane tension. Here we propose a scheme to calculate the free energy change associated ...

Core-shell nanoparticles consisting of silica as core and surface-grafted poly(dimethylsiloxane) (PDMS) as shell with different diameters were prepared and used as heterogeneous nucleation agents to obtain CO2-blown poly(methyl methacrylate) (PMMA) nanocomposite foams. PDMS was selected as the shell material as it possesses a low surface energy and high CO2-philicity. The successful synthesis o...
