On the Elastic Moduli of Unidirectional Fibre Reinforced Composites
A simple analytical technique is presented for obtaining lower bounds to the effective moduli of unidirec-tional fibre-reinforced composites with any repetitive array of fibres. The analysis depends upon a direct method involving stress-equilibrium and strain-continuity considerations, and thus it differs from the type of analysis due to Hashin and Hill (and others) involving variational method...
متن کاملBlast resistance of unidirectional fiber reinforced composites
Three-dimensional transient deformations of a laminate comprised of several unidirectional fiber reinforced layers perfectly bonded to each other and subjected to a blast load are analyzed by the finite element method with an in-house developed, verified and fully validated code with rate-dependent damage evolution equations for anisotropic bodies. The continuum damage mechanics approach employ...
متن کاملFinite element modelling of creep deformation in fibre-reinforced ceramic composites
The tensile creep and creep-recovery behaviour of a unidirectional SiC fibre-Si3N4 matrix composite was analysed using finite element techniques. The analysis, based on the elastic and creep properties of each constituent, considered the influence of fibre-matrix bonding and processing-related residual stresses on creep and creep-recovery behaviour. Both twoand threedimensional finite element m...
متن کاملA time dependent model for unidirectional fibre-reinforced composites with viscoelastic matrices
In this work, a fully three-dimensional constitutive model suitable for the macroscopic description of unidirectional fibre-reinforced composites where the matrix exhibits a time-dependent viscoelastic behaviour is developed. Specifically, we consider a coordinate-free formulation where the stress and strain fields can be decomposed into fibre-directional and volumetric parts on the one hand, a...
متن کاملOil-Palm-Fibre Reinforced Phenolformaldehyde Composites
Thermophysical properties such as, effective thermal conductivity (A,,) and effective thermal diffusivity (Xc) of untreated reinforced phenol formaldehyde with different weight per centages of oil-palmfibre (x) are measured simultaneously using the transient plane source (TPS) technique between 80 to 120"C. The composites investigated contain 20, 30 and 50 weight per centage of oil-palm-fibre. ...
