Composite Reinforcement

The numerical simulation of composite forming permits to envisage the feasibility of a process without defect but also to know the directions of the reinforcements after shaping. These directions condition strongly the mechanical behaviour of the final textile composite structure. In addition, the angles between warp and weft yarns influence the permeability of the reinforcement and thus the filling of the resin in the case of a liquid moulding process. The forming of composite reinforcement can be made on a single ply or simultaneously on several plies. In this paper the different approaches for the textile reinforcement forming simulation are described. A three node element with arbitrary directions of the yarns with regard to the element sides is presented and used for the simultaneous hemispherical forming of three layers.

Negative Effect

Adhesive anchor is an effective tool for a steel-to-concrete connection combined with the way of post-installed anchorage. However the bond strength of adhesive will decrease at elevated temperature which has a negative effect on anchorage behavior. In this paper a numerical analysis with 3D FE model has been carried out to investigate the tensile performance of adhesive anchor in a steel-to-concrete connection subjected to fire and the results show that high temperature have significant impact on bond strength of anchor even with the protection of fire resisting coating covering the surface of concrete base and the bond stress does not distribute along anchor length during the process of heating. The tensile strength of adhesive anchor presents a great reduction at elevated temperature compared with the strength in normal temperature.
