摘要: Abstract A novel homogenisation method for heterogeneous structures containing a twist symmetry by means of RVEs with twisted-periodic boundary conditions is introduced. The considers finite deformations and applied to hybrid-yarn reinforced elastomers in order compute the macroscopic elastic behaviour failure surface. excellent numerical efficiency parallelisability are shown comparison two classical methods. The yarn modelled modified approach Criscione et al. (2001) terms an alternative set physically based strain invariants. Its definition preserves advantages invariants while allowing straight forward derivation stress material tangent within framework element method.
