The equations of motion the Euler–Bernoulli and Timoshenko beam theories are reformulated using nonlocal differential constitutive relations Eringen [International Journal Engineering Science 10, 1–16 (1972)]. then used to evaluate static bending, vibration, buckling responses beams with various boundary conditions. Numerical results presented bring out effect behavior on deflections, loads, natural frequencies carbon nanotubes.
Replacing micro-reinforcing fibers with carbon nanotubes (CNTs) is beneficial for improving the impact properties of ultra-high performance concrete (UHPC); however, weak wettability and dispersibility CNTs weakly bonded interface between UHPC limit their effectiveness as composites. Therefore, this study aims to enhance reinforcement effect on via functionalization. Unlike ordinary CNTs, functionalized carboxyl or hydroxyl groups can break Si–O–Ca–O–Si coordination bond in C–S–H gel form a...
In mechanical design as well protection from various natural hazards, one must ensure an extremely low failure probability such 10(-6). How to achieve that goal is adequately understood only for the limiting cases of brittle or ductile structures. Here we present a theory do transitional class quasibrittle structures, having constituents and characterized by nonnegligible size material inhomogeneities. We show distribution strength representative volume element governed Maxwell-Boltzmann...
Triggered by newly formed defects (such as cracks) in the host materials, self-healing systems have ability to effect healing automatically and thereby delay or prevent subsequent damage. Self-healing materials been conceptualised researched upon recent years but difficulty implementation has delayed its prevalent usage. One difficult medium which yet be implemented widely practice is concrete. The casting of concrete causes vibration impact aggregates on system curing shrinkage thermal...
