Abstract: The purpose of the project was to design and simulate a window assembly to be used in GISAX/GIWAX1 experiments. The window lies between the sample and theWAXS2 detector, a modified, in-vacuum detector, with modules removed to allow scattered radiation to pass through to a SAXS3 detector positioned downstream. The window uses 75 μm thick Kapton® HN film and given the size, pressure and the short distance to the sensors, it was necessary to support it on a frame. To avoid any information loss from shadowing of the detector, a frame was designed so that shadows will be projected into the gaps between the detector modules. The geometry was such that DMLS4 was an effective way of producing the item. Given the slenderness of the structure and the forces it supports, the material approaches or exceeds its yield point, so a bilinear, isotropic, hardening material model was chosen; moreover, large deflections were enabled. Also, the contacts were modelled with augmented Lagrange frictional formulation. All these assumptions made the analysis strongly non-linear.
