During casting of concrete cube specimens of 200 mm, steel bars of 12-mm in diameter and 50-mm in length were embedded...

... ABSTRACT: Large aggregate concrete is usually used in the mass offshore concrete structures. This paper presents the behavior of large aggregate concrete and sieved concretes under biaxial stress states. The tests are carried out on large size specimens of 25 × 25 × 40cm and 25 × 25 × 25cm...

... of the retardation after a single overloading increased with a decrease in a/W and an increase in alb, and %O L. These phenomena are related to the change of the micro-crack growth direction and the crack branching in near-surface area of the specimen. It was difficult to explain the retardation after a single...

With this in view, a number of specimens with different microstructures were prepared and observed by both...

... ABSTRACT: Currently adopted modified-WOL specimen has difficulty in producing fatigue precrack. And Ktscc evaluation using the analytic compliance formula has many problems. Hence, Oh and Kim(1989) have designed such a specimen geometry as mixed modified-WOL with CT types. and proposed...

The duplex steel coupons subjected to pure HZ 5 at 120°C to Z400C for 8 and Z4 hours showed no appreciable weight change whereas at 500°C and 550°C for the same...

... ABSTRACT: The effect of hardener on the tensile fracture behavior of carbon fiber reinforced plastic, CFRP, was investigated using smooth and notched tensile specimens at various temperature ranges. The hardeners used were an acid anhydride and an amine line. Experimental results were...
