ine In the design of light components, materials and cross-section shapes govern structural efficiency. They are crucial reason, it is not surprising that they were the focus of This paper presents a novel strategy to support the selec-tion of materials, cross-sectional shapes and their co-selec-tion. The framework of the method is underpinned by the concept of shape transformers [8,9]. Shape transformers are dimensionless parameters defined to measure geometric quantities of a cross-section regardless of size. In bendin
