© SimBAU Last updated:	Glass Products of glass are manufactured in Germany industrially in large quantities. The cut procedures, essentially scratching of the glass and bend breaking, used here, make a complex rework necessary and frequently lead to defective Drinking glasses, porcelain, tubing laserseparately components. The IWM therefore develops procedures for the laser cutting of bottle glasses and now also flat glasses by introducing of thermo stresses which causes a plain cut surface. The interfaces are rework-free and of a high quality. Grinding, cleaning can be avoided this way Numeric simulation is an important aid when developing these procedures. In the automotive sector bonded windshields of group safety glass (VSG discs) glued into the frame are basic elements and increase the rigidity of the structure. For the numeric Crash simulation on the basis of existing failure models (BRITTLE CRACKING MODEL) we develop experimentally verified procedures which describe the failure of VSG windshields with sufficient accuracy.
