Tensile and fatigue properties of as-rolled and annealed polycrystalline Cu foils with different thicknesses at micrometer scale are investigated. Uniaxial tensile testing shows that with decreasing foil thickness the uniform elongation decreases for both as-rolled and annealed foils, while the yield strength and ultimate tensile strength increase for as-rolled foils, but those decrease for the...

This study investigates the effect of moisture conditioning on the Indirect Tensile Strength (ITS) of asphalt concrete. As a first step, cylindrical samples of 100 mm diameter and 50 mm thick were prepared using a Superpave gyratory compactor. Next, the samples were conditioned using Moisture Induced Susceptibility Test (MIST) device at different numbers of moisture conditioning cycles. In the ...

As an emerging advanced construction material, strain hardening cementitious composite (SHCC) has seen increasing field applications in recent years. Reliable data on tensile properties, including tensile strength and tensile strain capacity, are needed for structural design and for quality control. However, existing uniaxial tensile tests are relatively complicated and sometime difficult to im...

Generally, fatigue failure in an element happens at the notch on a surface where the stress level rises because of the stress concentration effect. The present paper investigates the effect of a notch on the fatigue life of the HSLA100 (­high strength low alloy) steel which is widely applicable in the marine industry. Tensile test was conducted on specimens and mechanical properties were obtain...

In this study, fatigue test and crack propagation analysis of welded joints in ships and offshore structures were performed. The test models have two types of welded joints, T-joint and double plate. Test data is presented in S-N curves obtained by the Hot Spot Stress (HSS) approach. The S-N data for each length of crack were appraised to define the fatigue life of crack initiation and propagat...

Fatigue behaviors of structural adhesives composed of epoxide resin and aliphatic α, ω-dicarboxylic acids HOOC-(CH2)p-COOH (p=2, 4, 8 or 10) were investigated by analyzing the results of fatigue test and bulk properties of the systems. The fatigue strength and maximum value of damping increased with increasing p. The glass transition temperature, tensile strength, shear adhesive strength by ten...
