摘要: Unidirectional fiber-reinforced elastomers are investigated. A respective finite strain model is formulated within the couple stress theory, and a specific new form of energy density implemented for three-dimensional element analysis. The homogeneous anisotropic based on kinematics constitutive equations proposed by Spencer Soldatos (International Journal Non-Linear Mechanics 42:355–368, 2007) includes additional material parameter regulating bending stiffness regardless its tensile stiffness. procedure determination offered case simple beam under small strains. Numerical simulations four-point test presented to demonstrate advantage model.
