Реферат:
Mechanical behaviour of pre-stressed fbre-reinforced composites is modelled in a geometrically exact setting. A general
approach which includes two diferent reference confgurations is employed: one confguration corresponds to the load-free
state of the structure and another one to the stress-free state of each material particle. The applicability of the approach is
demonstrated in terms of a viscoelastic material model; both the matrix and the fbre are modelled using a multiplicative
split of the deformation gradient tensor; a transformation rule for initial conditions is elaborated and specifed. Apart from its
simplicity, an important advantage of the approach is that well-established numerical algorithms can be used for pre-stressed
inelastic structures. The interrelation between the advocated approach and the widely used “opening angle” approach is
clarifed. A full-scale FEM simulation confrms the main predictions of the “opening angle” approach. A locking efect is
discovered: in some cases the opening angle of the composite is essentially smaller than the opening angles of its individual
layers. Thus, the standard cutting test typically used to analyse pre-stresses does not carry enough information and more
refned experimental techniques are needed.
