A thin walled open channel beam subjected to a 3-point bend and constant velocity boundary condition is investigated to establish its potential to validate material performance for automotive crash applications. Specifically quantitative validation of material tensile data determined from high speed tests and component models, and qualitative validation of materials resistance to fracture. Open channel beams are fabricated from structural grade sheet steel and aluminium alloy and tested at quasi-static and higher speeds up to 10 m/s and in all cases, large displacement in which deformation involves formation of a plastic hinge. This paper describes development of the validation test procedure, specifically design of specimen, system of measurement and boundary conditions, using numerical techniques and experimentation. The new test procedure will increase confidence in the modelling and introduction of new advanced higher strength materials in automotive crash structures.
