[ad_1] Abstract Coordination number (CN) is a fundamental microscale variable in soils affecting the macroscale parameters of the material such as porosity, stiffness under loading, and stability under hydraulic gradients. However, most studies on CN have focused on sphere or ellipsoid packings using the discrete element method (DEM). By means of computed tomography (CT) and…

[ad_1] Abstract This paper reports the characterization of internal damping ratio ( ξ ) and Q factor of ultrahigh-performance fiber-reinforced concrete (UHPFRC) using acoustic tests for undamaged and damaged samples excited by an impact. Ratio ξ is a nondimensional parameter that measures the material capacity to dissipate vibration, and the Q factor is physically interpreted…

[ad_1] The rate of uptake of metal AM is not as fast as many predicted even just a few years ago, because AM — particularly when using metal — comes with a number of limitations. When considering the existing two PBF technologies — laser PBF and traditional eBeam PBF — NeuBeam offers a new way,…

[ad_1] Abstract This paper presents the results of the flexural testing to destruction of two cast iron girders preserved during the demolition of a railway bridge in Scotland. The 151-year-old girders were reinforced with ultrahigh modulus carbon fiber polymer composite (CFRP) plates in 2004. The CFRP plates on one girder were damaged during the demolition…
