Ultra high performance concrete and C-FRP tension Re-bars: A unique combinations of materials for slabs subjected to low-velocity drop impact loading

Frontiers in Materials, Год журнала: 2022, Номер 9

Опубликована: Ноя. 21, 2022

In this research work, different combinations of normal strength concrete (NSC), ultra-high-performance (UHPC), and steel fiber-reinforced UHPC (SFR-UHPC) with re-bars conventional carbon polymer (C-FRP) are used in a two-way square slab size 1000mm x 75mm subjected to 2500 mm free-fall impact loading. Experimental arrangement consisting 105 kg dropping weight the circular flat impacting face 40 diameter for carrying out test is modeled using high-fidelity physics-based finite element computer code, ABAQUS/Explicit-v.6.15. After validating experimental results NSC bars, analyses extended by replacing bars UHPC/SFR-UHPC C-FRP respectively, under same weight. Only remote (tension face) slabs provided re-bars. Widely employed available ABAQUS, Concrete Damage Plasticity model strain-rate effects has been entrusted simulating plastic response. Re-bars idealized Johnson-Cook plasticity damage model. defined classical following elastic-plastic constitutive laws. The responses NSC/UHPC/SFR-UHPC steel, considered discussed compared. Slabs made found offer promising combination materials withstand low-velocity load little extraordinary performance.

Torsional vibration of a flexoelectric nanotube with micro-inertia effect

Mechanics of Advanced Materials and Structures, Год журнала: 2023, Номер 31(17), С. 4019 - 4036

Опубликована: Март 20, 2023

The modified strain gradient theory (MSGT) with flexoelectric and micro-inertia effects is developed to study the free vibration of tube made elastic centrosymmetric materials. Within this theory, internal energy density function tensor, deviatoric part stretch rotation tensors, dilatation gradient, polarization vector, electric quadrupoles. linear coupled governing equations boundary conditions are derived from Hamilton variation principle. torsional problem analytically solved for non-piezoelectric nanotube fixed edges. effect geometry, coefficient, micro-inertia, micro-stiffness parameters on natural frequency studied.
