The model shows a turbine rotor that was developed to demonstrate the simulation of failing structural components using the “Modify Stiffness” feature. It illustrates how failure situations can be simulated by selectively deactivating and varying surface stiffnesses. The individual parameters – deactivate, surface, stiffness, and modify – are used in a precise way to analyze the behavior of the rotor. In addition, the linked image provides a schematic representation of the turbine rotor, with a focus on the shape and arrangement of the blades.
