TL;DR: In this paper, the effect of high temperature on cement-based materials containing fly ash and nanosilica has not been well characterized, and the porosity was determined using the BET (Brunauer, Emmett, and Teller) technique to study the specimens' behavior after exposure to high temperatures.

TL;DR: In this article, a composite bipolar plate for a polymer electrolyte fuel cell has been prepared by a bulk-moulding compound (BMC) process, where the graphite size is decreased from 1000 to 177μm to less than 53μm.

TL;DR: The behavior of short and relatively deep reinforced concrete beams, which occur in shear walls of multistory structures, and the damage or failure of which has been observed in recent earthquakes, is examined in this paper.
Abstract: The behavior of short and relatively deep reinforced concrete beams, which occur in shear walls of multistory structures, and the damage or failure of which has been observed in recent earthquakes, is examined. Experimental and analytical studies indicate that their ultimate flexural capacity is reduced by large shearing forces, even if a diagonal tension failure is prevented by adequate web reinforcement. After diagonal cracking, the distribution of internal forces radically differs from that observed in beams of normal proportions. The flexural reinforcement is found to be in tension in areas where compression is expected, and this affects the beam's ductility. Shear deformations of diagonally cracked coupling beams greatly overshadow those causd by flexure. With the aid of a model of the cracked beam its stiffness can be approximated. This satisfactorily agrees with observations which indicate that the stiffness after cracking is less than 20% of the stiffness of uncracked coupling beams.

TL;DR: In this paper, the behavior of part-through flaws with regard to failure under monotonic loading and their growth under fatigue loading was studied experimentally and analytically, and the results of fracture toughness data and results of life prediction using the NASA/FLAGRO program were presented.
Abstract: The behavior of part-through flaws with regard to failure under monotonic loading and their growth under fatigue loading was studied experimentally and analytically. Comparisons are made of experimental values of toughness obtained using surface and corner cracked specimens with those obtained using standard test specimens, and also experimental growth cycles were compared with numerical predictions using the NASA/FLAGRO computer program. Tests were conducted on various types of surface and corner cracks under tensile and bending loads. Room temperature lab air provided the test environment. The material used in this study was the Ti-6Al-4V alloy in the solution treated and aged (STA) and stress relieved condition. Detailed tabulation of the fracture toughness data and results of life prediction using the NASA/FLAGRO program are presented. Fatigue crack growth rates for the part-through cracked specimens are compared with a base curve fitted from the data obtained using standard specimens. The fatigue loading used in the crack growth testing was constant-amplitude sinusoidal type.
