A theoretical formulation and the analysis of heat conducting fibre‐reinforced structures are shown herein. Viscoelastoplastic behaviour at infinitesimal strain is considered in the context of non‐equilibrium irreversible thermodynamics. To demonstrate the theory, a fibre‐reinforced cylindrical rod subjected to a dynamic axial load is solved via the finite elements. Strain hardening of both fibres and matrix media is incorporated in the analysis. The results clarify the relationships of energy dissipation resulting from viscoelasticity, plasticity, or the combined effects with respect to orientation of the fibres.
