| Fatigue analysis uses the cumulative damage approach to estimate fatigue life from stress or strain time histories. Estimation is accomplished by reducing data to a peak/valley sequence, counting the cycles and calculating fatigue life. A library containing standard fatigue material properties is provided. Optimization Optimization is a process that helps the analyst arrive at the best solution for a given design goal. NX Advanced FEM allows the user to create an optimization solution process. The user can define a goal such as the mass of a part or component, a constraint such as maximum allowable Von Mises stress and the design parameter(s) to vary on the component. The optimization solution process will run based on the design criteria while varying the design parameters to enable the design engineer to determine if there is a better structural design alternative vs. the original baseline design. Product availability NX Advanced FEM is a core package in the suite of NX Advanced Simulation add-on applications available within the Siemens Lifecycle Simulation architecture. It is a prerequisite for all other solution applications in the NX Advanced Simulation suite such as NX Nastran Desktop, NX Flow, NX Thermal, NX Electronic Systems Cooling, NX Space Systems Thermal, NX Response Simulation, NX Laminate Composites and the customized solver environments for Nastran, Ansys and Abaqus. NX Advanced FEM is available on most major hardware platforms and operating systems (Windows, Linux, UNIX) including selected 64-bit systems. |
