Abstract The servohydraulic biaxial testing machines of the Essen Laboratory for Lightweight Structures (ELLF), Institute for Metal and Lightweight Structures of University of Duisburg‐Essen, have maximum loading capacities of 20 kN and 50 kN. Cruciform test specimens are used to investigate the stress‐strain‐behaviour of woven textile fabrics and foils in order to determine the material stiffness properties or compensation values. The cruciform test specimens are biaxially loaded in the plane of the fabric. Hereby, the warp and weft directions are loaded cyclically by stresses or strains simultaneously (see pp. 222−229).
