Nichtlineare Verformung einachsig belasteter Gewebe

The previous practice of the construction and optimization of woven fabrics for technical applications required in-depth expertise and considerable testing expenditures to verify the mechanical properties of the fabrics. This thesis presents a simulation program allowing a reliable calculation of the non- linear deformation of woven fabrics under tensile stress. The calculations are based on the finite elements method, whose procedures and algorithms have been adapted, or newly developed, to conform to the special requirements of the fabric calculation. To allow for an application-oriented utilization and easy handling of the program, all data entry will follow the usual principles and guidelines for fabric construction. The calculation results for technical woven fabrics, considering different weaves, as well as different materials, clearly show that our development target has been achieved. The accuracy of all the calculated variations is sufficiently high to describe the force-elongation characteristics, as well as the values of the peak tension and the elongation at peak tension. Especially the range of initial strain; which, due to the fabric crimp, deviates strongly from the fiber characterization , is well displayed by the simulation program. Based on this newly developed simulation environment weaving mills could reduce the personnel intensive and time consuming weaving tests, used to determine the mechanical properties of woven fabrics. Furthermore it is possible to optimize the material usage by a load determined dimensioning of the woven fabric
