FRACTURE MECHANISM OF PLAIN CONCRETE UNDER UNIAXIAL TENSION

Uniaxial Tension Test of Slender Reinforced Early Age Concrete Members

The present study aims to obtain the tensile properties of early age concrete based on a uniaxial tension test employing RC slender members. First, the paper shows that concrete strain is equal to the strain of rebar at the mid-span of the RC member. The tensile Young's modulus and the strain capacity of early age concrete are estimated using strain measurements. The experiment indicated that t...

Effect of edge structures on elastic modulus and fracture of graphene nanoribbons under uniaxial tension

Qiang Lu and Rui Huang Department of Aerospace Engineering and Engineering Mechanics, University of Texas, Austin, Texas 78712, USA ABSTRACT Based on atomistic simulations, the nonlinear elastic properties of monolayer graphene nanoribbons under quasistatic uniaxial tension are predicted, emphasizing the effect of edge structures (armchair and zigzag, without and with hydrogen passivation). T...

Deformation micromechanisms of collagen fibrils under uniaxial tension.

Collagen, an essential building block of connective tissues, possesses useful mechanical properties due to its hierarchical structure. However, little is known about the mechanical properties of collagen fibril, an intermediate structure between the collagen molecule and connective tissue. Here, we report the results of systematic molecular dynamics simulations to probe the mechanical response ...

Scattering amplitude of a single fracture under uniaxial stress

Remotely sensing the properties of fractures has applications ranging from exploration geophysics to hazard monitoring. Newly-developed capabilities to measure the in-plane component of dense laser-based ultrasound wave fields allow us to test the applicability of a linear slip model to describe fracture properties. In particular, we estimate the size, and the normal and tangential compliance o...
