Originální abstrakt

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