Improving the accuracy of virtual prototypes helps to shorten product development times and reduces the number of physical prototypes required. One way in which the accuracy of crash analysis can be improved is to include the effects of forming in the material properties. Corus has developed a three-step 'Forming to Crash' process to account for formed properties in crash analysis during both concept and detailed vehicle design stages. The first step uses a selection procedure to identify the parts most sensitive to the inclusion of formed properties. The second step uses an approximate 'Forming to Crash' method to rapidly estimate the formed properties and reduce the time taken to conduct the analysis during concept design. The third step links a detailed forming analysis to a crash analysis to provide a full 'Forming to Crash' technique for use during detailed design development. This three-step process is used by Corus to support customers in the application of advanced high strength steels. Including formed properties in vehicle body structure can have a considerable influence on collapse modes of these components and, importantly, a significant influence on the energy absorbed by surrounding components. The Corus 'Forming to Crash' three-step process enables time-efficient inclusion of formed properties in crash analysis during both the concept and detailed design stage. The process uses a selection procedure, in combination with expertise in materials and form-Ing, to provide rapid assessment of the sensitivity of a structure to formed properties. Detailed design is then supported through the use of full forming simulation linked to the major crash analysis codes. 'Forming to Crash' has now become a feasible design analysis process and is one of a range of advanced material modelling techniques developed by Corus to support customers in the application of advanced high strength steels.
