Coupling Mechanical and Electrical Behavior in the Multi-scale Simulation of Polymer-based CNT Nanocomposites

A numeric model has been proposed to investigate the mechanical and electrical properties of a polymeric/carbon nanotube (CNT) composite material subjected to a deformation force. The reinforcing phase affects the behavior of the polymeric matrix and depends on the nanofiber aspect ratio and preferential orientation. The simulations show that the mechanical behavior of a computer generated material (CGM) depends on fiber length and initial orientation in the polymeric matrix. It is also shown how the conductivity of the polymer/CNT composite can be calculated for each time step of applied stress, effectively providing the ability to simulate and predict strain-dependent electrical behavior of CNT nanocomposites.

Resistência II: Direito Fundamental Constitucional

Invocava então o art. 21º da CRP. “Todos têm o direito de resistir a qualquer ordem que ofenda os seus direitos, liberdades e garantias e de repelir pela força qualquer agressão, quando não seja possível recorrer à autoridade pública”: art. 21º da Constituição. § Then invoked the art. 21 of the CRP. "Everyone has the right to resist any order that offends the rights, freedoms and guarantees and to resist by force any aggression when it is not possible to use public authority" means art. 21 of the Constitution.
