Summary

An original finite element technique to include fibres within laminated plates and shells that does not increase the number of degrees of freedom is proposed and tested for nonlinear dynamic analysis considering plasticity. This technique enables the separate use of matrix and fibre mechanical properties naturally resulting in the reinforced continuum behavior. The proposed finite element formulation is the total Lagrangian, based on positions and generalized vectors, which implies constant mass matrix allowing the use of the Newmark time integrator conserving energy in elastic problems developing large displacements. The constitutive model of the matrix material is elastoplastic and combines the Tsai-Wu and the Drucker-Prager surfaces. This model enables the comparison of the proposed fibre inclusion technique and the homogenization procedure. Selected examples are chosen to validate the formulation and results are compared to reference values available in literature.
