Mechanical Modelling of Wire Reinforced Metal Matrix Extrusion Profiles

Abstract

Compound extruded unidirectionally reinforced profiles are heterogeneously reinforced metal matrix composites. Profiles made from this material show a different mechanical behaviour than classical composite components. Homogenized material properties are required for an efficient design process. Within this paper an approach is shown to provide homogenized data for stiffness and strength for compound-extruded components. The usability of the Tsai-Hill failure criterion is investigated, and shown for cases with negligible residual stresses. Load cases including thermal stresses cannot be investigated by the Tsai- Hill failure criterion. Within the failure investigation a procedure is shown to include residual and thermal stresses.
