A static analysis calculates the effects of steady loading conditions on a structure, while ignoring inertia and damping effects, such as those caused by time-varying loads. A static analysis can, however, include steady inertia loads (such as gravity and rotational velocity), and time-varying loads that can be approximated as static equivalent loads (such as the static equivalent wind and seismic loads commonly defined in many building codes). Static analysis determines the displacements, stresses, strains, and forces in structures or components caused by loads that do not induce significant inertia and damping effects. Steady loading and response conditions are assumed; that is, the loads and the structure’s response are assumed to vary slowly with respect to time

Structural nonlinearities occur on a routine basis. For example, whenever you staple two pieces of paper together, the metal staples are permanently bent into a different shape . Common Examples of Nonlinear Structural Behavior (a). If you heavily load a wooden shelf, it sags more and more as time passes, as shown in Figure (b). As weight is added to a car or truck, the contact surfaces between its pneumatic tires and the underlying pavement change in response to the added load, as shown in Figure (c). If you were to plot the load-deflection curve for each example, you would discover that they exhibit the fundamental characteristic of nonlinear structural behavior: a changing structural stiffness

Free Vibration (modal)

Use modal analysis to determine the vibration characteristics (natural frequencies and mode shapes) of a structure or a machine component while it is being designed. It can also serve as a starting point for another, more detailed, dynamic analysis, such as a transient dynamic analysis, a harmonic analysis, or a spectrum analysis

Harmonic Analysis

Any sustained cyclic load will produce a sustained cyclic response (a harmonic response) in a structural system. Harmonic analysis gives you the ability to predict the sustained dynamic behavior of your structures, thus enabling you to verify whether or not your designs will successfully overcome resonance, fatigue, and other harmful effects of forced vibrations.

Transient Analysis

Transient dynamic analysis (sometimes called time-history analysis) is a technique used to determine the dynamic response of a structure under the action of any general time-dependent loads. You can use this type of analysis to determine the time-varying displacements, strains, stresses, and forces in a structure as it responds to any combination of static, transient, and harmonic loads. The time scale of the loading is such that the inertia or damping effects are considered to be important.

This type of analysis involves application of structural and thermal loads to the same model. The model is first analyzed by application of  structural load and then subjected to thermal loads . We have 2 methods to perform this analysis

  1. Sequential Method

The sequential method involves two or more sequential analyses, each belonging to a different field. You couple the two fields by applying results from the first analysis as loads for the second analysis. An example of this is a sequential thermal-stress analysis where nodal temperatures from the thermal analysis are applied as “body force” loads in the subsequent stress analysis.

2. Direct Method

The direct method usually involves just one analysis that uses a coupled-field element type containing all necessary degrees of freedom. Coupling is handled by calculating element matrices or element load vectors that contain all necessary terms

Fatigue is the phenomenon in which a repetitively loaded structure fractures at a load level less than its ultimate static strength. For instance, a steel bar might successfully resist a single static application of a 300 kN tensile load, but might fail after 1,000,000 repetitions of a 200 kN load.

The primary factors that contribute to fatigue failures include:

  • Number of load cycles experienced
  • Range of stress experienced in each load cycle
  • Mean stress experienced in each load cycle
  • Presence of local stress concentrations

Buckling analysis is a technique used to determine buckling loads (critical loads at which a structure becomes unstable) and buckled mode shapes (the characteristic shape associated with a structure’s buckled response).

Two techniques are available in the ANSYS Multiphysics, ANSYS Mechanical, ANSYS Structural, and ANSYS Professional programs for predicting the buckling load and buckling mode shape of a structure: nonlinear buckling analysis, and eigenvalue (or linear) buckling analysis

  • Buckling analysis of columns

Computational fluid dynamics (CFD) is an engineering method that calculates flow fields and other physics in detail for an application of interest. ANSYS uses a multidisciplinary approach to simulation in which fluid flow models integrate seamlessly with other types of physics simulation technologies. The CFD, or fluids, simulation results can be used as part of a Simulation Driven Product Development process — to illustrate how a product or process operates, to troubleshoot problems, to optimize performance and to design new product

The primary ANSYS solution products in the fluids area are FLUENT and CFX. With these solutions you can simulate a wide range of phenomena: aerodynamics, combustion, hydrodynamics, mixtures of liquids/solids/gas, particle dispersions, reacting flows, heat transfer, etc. Steady-state and transient flow phenomena are easily and quickly solved.
