The objective of this task was to develop new PIPER Child models. The basis for the development was mainly the LBMC models available before PIPER (Beillas et al., 2013, 2014). Extensive modifications were performed within the project, and little is actually remaining of the original version. New head, neck, pelvis and lower extremities were developed, while the shoulder and trunk were extensively modified and improved. While some minor modifications are expected until the end of the project as a result of the model use and extension of the validation matrix, the main development phase is now completed and the model can be considered as final. As the deliverable is the model (and not the report), the text provided in this report summarizes some of the developments contributed by the project partners. As a summary, the contributions of the partners include: KTH: new head and neck models, assembly and coordination of the model evolutions; work on the scaling scripts, work on the flesh meshing for the whole body, renumbering and renaming, debugging, validation for head, neck, and initiation of full body runs UCBL: segmentation and work on the skin envelope for trunk and lower extremities, lower extremities scaling and assembly, shoulder model, trunk anatomical improvement and remeshing, debugging, transfer of scaling approach to KTH, trunk validation for regional loading in frontal and side impact (from shoulder to pelvis) TUB: pelvis and lower extremity skeletal meshing; diaphysis validation for tibia, fibula and femur. While not contributing directly to the model, PDB did the first set of metadata to be able to load the model into the PIPER tool. Contributions of other partners for the integration of the scaling in the PIPER tool include mainly CEESAR and UCBL. In the upcoming months until the end of the project, more detailed descriptions of the model will be provided in the manual. The model (and all its validation setups which are currently being extended) will be released under an Open Source license on April 30, 2017 at the latest. The scaling approach will be extended to include material changes and all scaling tools will also be released under an Open Source license.
