Foundations in Structural Nonlinearities

Nonlinear behavior in structural responses of engineering systems is very common, and understanding different sources of nonlinearities and handling them properly is key to becoming a successful structural analyst. The treatment of nonlinearities is applicable to both static and dynamic analysis to study both stress and dynamic response of structures. In this learning track, the simulation experts at Ansys have created a list of courses that provide all the fundamentals necessary to understanding and handling different types of nonlinearities in structural analysis. This track focuses on the use of Ansys Mechanical, but the covered theoretical concepts are also applicable to other commercial finite element solvers.

Structural Nonlinearity

All structures respond to external loads in a nonlinear fashion. However, the nonlinear nature is profound and important in only certain cases. There are several linear and nonlinear solvers that are available to analyze these systems and picking the correct solver is ofte...Read more

Large Deformation

Solids behave differently when they are subjected to large deformations as opposed to small ones. This is due to the change in their shape and it often introduces a form of nonlinearity known as geometric nonlinearity. The degree to which this nonlinearity affects the solution ...Read more

Computational Considerations

Solving a problem and computing to achieve a final product requires many iterations. The more complex the problem, the more iterations are required. In this course, we will focus on how Ansys software solves a simulation problem and the computatio...Read more

Metal Plasticity

Metals have played an important role in the development of technology throughout history. One of the preferred features of metals is their ductility, which is the ability to deform under loads without fracture. Such behavior can no longer be captured by a simple linear stress-str...Read more

Hyperelasticity

While most conventional metals undergo plastic deformation at very small to moderate strains, there is a class of non-metallic materials that can exhibit elastic behavior at strains as high as 30% or more, while developing very little or no detectable plastic strain. In this Ansys...Read more

Structural Instabilities

Structural instability is a phenomenon where a structure deforms a lot while the external force increases by a small amount. In this Ansys Innovation Course on “Structural Instabilities”, we will present a focused discussion on two categories of structural instability: dy...Read more
