Static Structural Analyses

Static structural analyses permit the prediction of deflection, temperature, strain and stress distributions within a component / assembly. This is the most common analysis performed for verification / validation but does not mean that they are always simple in nature. These have evolved to include complex interactions within the analysis (contacts, joints, composites) to linking with other physics (fluid-structure, electromagnetic-structure). Significant performance insight into a component / assembly can be obtained from a static simulation.

Dynamic Analyses

Dynamic analysis allows the user to account for the time dependent characteristics of their structure. For linear dynamics, the initial effort is often to determine the natural frequencies through a modal analysis. Results are then utilized in a harmonic, shock, seismic, random vibration or transient simulation to determine deflections, stresses and strains. For nonlinear dynamics, a direct transient simulation can be performed.

Thermal Analysis – Thermal Stress

Accurate prediction of temperature distributions is critical to performing a thermal stress analysis. Forces generated by thermal expansion can be significant and proper analysis techniques need to be implemented. With ANSYS’s capabilities in conduction, convection, radiation, temperature dependent material models, and internal heat generation, complex systems can be accurately simulated. These can be further advanced by performing FSI with a CFD model.

Durability and Fatigue – Failure Analysis

Component failures are often not due to a single event, but due to accumulative damage caused by a series of events. The typical fatigue process is to maintain stress / strain levels below the allowable for the required number of cycles. Multiple loads often occur and will have a different cycle requirement. ANSYS Fatigue, or the more advanced nCODE can predict the component life. An alternative approach is to understand that a crack exists in the component. The crack is analyzed to determine whether it will propagate, and if so, at what rate.

Optimization

Markets have become significantly more competitive and having small gains in performance can make or break success. Optimization can be measure in many ways, cost, weight, deflection, pressure drop and life are but a few. By either parameterization or topological optimization designs can be improved to their maximum potential.

The siblings to optimization are sensitivity and robustness. Some designs may have great performance under ideal manufacturing and environmental conditions, but minor variations quickly degrade this. Often the best design isn’t the one that has the best performance for one condition, but has good performance over a variety of conditions. It should be noted that this can be used to reduce costs as well. Maintaining tight machine tolerances will increase costs. It the design is not sensitive to this variable, these can be opened up.
