Stefan Harries 3 Report post Posted June 12, 2013 Hi, In case you want to play with optimization strategies without the need to couple CAESES / FRIENDSHIP-Framework to any outside simulation code, you may want to use a simple example of a beam in bending. It uses beam theory for an I-beam, visualizing geometry, payload and weight. Just get started with the project file and a pdf with some explanations. A first DoE for a 10m beam with a payload of 10t yields 0.651 t for B=0.1813 m, H=0.4797 m and thick=0.0109 m. Maybe you will find something lighter that still fulfills all constraints?
