Abstract The tensile and compressive properties of hybrid basalt‐polypropylene fiber‐reinforced concrete (HBPFRC) under uniaxial load were investigated in this study. First, the influence mono‐basalt fibers, mono‐polypropylene fibers with different contents on stress–strain curve, strength, toughness analyzed. Second, constitutive equations proposed by Code GB 50010‐2010 used to fit curves, which good fitting results are obtained. Finally, mechanism HBPFRC discussed. indicated that better...
AbstractStarting from the innovative ideas of Chicco et al. (Vector optimization problems via improvement sets. J. Optim. Theory Appl. 2011;150:516–529), in this paper, concepts set and -efficiency are introduced a real locally convex Hausdorff topological vector space. Furthermore, some properties sets given kind proper efficiency, named as -Benson which unifies efficiency approximate is proposed optimization. Moreover, concept -subconvexlikeness set-valued maps an alternative theorem...
To investigate the effects of mixing polypropylene fiber different sizes and effect size on impact characteristics concrete, two fine one coarse were selected to design fabricate nine groups fiber-reinforced concrete test specimens by controlling ratio conducting a split Hopkinson pressure bar obtain stress–strain curves in various groups, their parameters such as elasticity modulus, peak strength, strain. The incorporation improved pre-peak properties extents. Strain hardening did not occur...
Creep characteristics are integral mechanical properties of rock salt and related to both long-term stability security repository. Rock creep studied in this paper through employing combined methods theoretical analysis numerical simulation with a nonlinear model the secondary development FLAC 3D software. A multistage loading was developed resulting calculations were found consequently coincide previously tested data.
Remaining useful life (RUL) is a crucial indictor to measure the performance degradation of machine tools. It directly affects accuracy maintenance decision-making, thus affecting operational reliability Currently, most RUL prediction methods are for parts. However, due interaction among parts, even all parts cannot reflect real whole machine. Therefore, an method needed. To predict machine, this paper proposes with dynamic objects based on meta-action theory. Firstly, tools decomposed into...
Abstract To study the influence of polypropylene fibers with different thicknesses on concrete beams, inclined section shear tests fiber beams were carried out. The cracking load, ultimate midspan deflection, reinforcement, and strain conventional reinforced-concrete under compared analyzed. load-bearing capacity rectangular was improved significantly by addition. Compared limit load multisize that reinforced three types increased 8.67% 17.07%, respectively. By mixing into initial crack...
