one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...

of skin tissue is highly interdisciplinary, involving bioheat transfer, burn damage, biomechanics and physiology. Characterization of the thermomechanical behaviour of skin tissue is of great importance and can contribute to a variety of medical applications. However, few quantitative studies have been conducted on the temperature dependent mechanical properties of skin tissue. This paper repor...

The compressive mechanical properties of uniform and density-graded Al-6061 foams, produced by replication of polymer foams, are measured. hile the uniform foam shows compressive behavior characteristic of conventional (uniform) metallic foams with a near constant plateau stress, he density-graded foam exhibits a smoothly rising plateau stress. This behavior is modeled using a simple series com...

Understanding structure-function relationships in the temporomandibular joint (TMJ) disc is a critical first step toward creating functional tissue replacements for the large population of patients suffering from TMJ disc disorders. While many of these relationships have been identified for the collagenous fraction of the disc, this same understanding is lacking for the next most abundant extra...

In this study, bulk ultrafine-grained and micro-crystalline cobalt was prepared using a combination of high-energy ball milling and subsequent spark plasma sintering. The average grain sizes of the ultrafine-grained and micro-crystalline materials were 200 nm and 1 μm, respectively. Mechanical properties such as the compressive yield strength, the ultimate compressive strength, the maximum comp...

In previous work, numerical experiments showed that ` minimization with 0 < p < 1 recovers sparse signals from fewer linear measurements than does ` minimization. It was also shown that a weaker restricted isometry property is sufficient to guarantee perfect recovery in the ` case. In this work, we generalize this result to an ` variant of the restricted isometry property, and then determine ho...

Due to their widespread availability, sandstones are commonly used as a natural stone for buildings, monuments and sculptures. In thecurrent study, nine sandstone samples from the Upper Red Formation (specified by the letters A, B, C, CG, S, S1, Sh, Tr and Min)were studied from a petrophysical point of view and their durability was evaluated. Then, their suitability as building stones wasassess...
